From: OP-SF Editors ,
Subject: New editors of (printed) Newsletter
Charles Dunkl, Chair of our Activity Group, has announced the appointment
of Renato Alvarez-Nodarse (Universidad Carlos III de Madrid) and Rafael
Yanez (Universidad de Granada) as co-editors of the Newsletter of the SIAM
Activity Group on Orthogonal Polynomials and Special Functions. They will
succeed Wolfram Koepf (HTWK Leipzig), and the next two issues will be
co-edited by the old and new editors. We look forward to working with
Renato and Rafael as much as we have enjoyed working with Wolfram over the
past three years.
Contact information for the new co-editors is in Topic #17 below.
Topic #2 ------------- OP-SF NET 5.2 ------------ March 15, 1998
~~~~~~~~~~~~~
From: OP-SF NET Editor
Subject: Minisymposium on Problems and Solutions in Special Functions
Our Activity Group will sponsor a Minisymposium "Problems and solutions in
Special Functions" (Organizers: Willard Miller, Jr. and Martin E.
Muldoon) during the SIAM Annual Meeting to be held in Toronto, July 13-17,
1998. (See OP-SF NET 5.1, Topic #3; the meeting web site is at:
http://www.siam.org/meetings/an98/an98home.htm).
The Minisymposium has been scheduled for 10:30 a.m. to 12:30 p.m. on
Tuesday July 14. Here is the description:
"Problem sections in journals such as SIAM Review and the American
Mathematical Monthly have been responsible for attracting many young
people to the mathematical profession, by providing them with concrete and
significant problems they can attack directly. Furthermore, problems
sections have traditionally been influential in advancing mathematical
research. At this time, when the SIAM Review is phasing out its problem
sections, it is appropriate to assess the history and impact of the
problems sections and their future evolution."
Speakers:
Cecil C. Rousseau, University of Memphis
"Problems on special functions contributed to the SIAM Review Problems and
Solutions section - a retrospective"
Abstract: not yet available
Otto G. Ruehr, Michigan Technological University
"Remarks on the SIAM Review Problem Section"
Abstract: not yet available
Willard Miller, Jr., University of Minnesota
"Remarks on the SIAM Review Problem Section"
Abstract: The speaker will serve a chair of a session of brief
presentations by invited members of the research community that has found
problem sections to be of great value. Included will be anecdotes on
interesting solved/unsolved problems that have appeared in problems
sections; new problems; the future evolution of problems sections.
Topic #3 ------------- OP-SF NET 5.2 ------------ March 15, 1998
~~~~~~~~~~~~~
From: OP-SF NET Editor
Subject: From opsftalk
Recent enquiries in opsftalk include the following query from Paul Nevai:
"Is this new (I hope)? If the measure is in the class M then there are
finitely many masspoints greater than 1 if and only if the ratio of the
consecutive ops evaluated at the point 1 converges to 1."
Three people (Victor Adamchik, John Boersma and Larry Glasser) have
provided answers to the questions posed by Bozidar Anicin on Bessel and
elliptic functions (OP-SF NET 5.1, Topic #1.)
Bruno Coste posted a question on an overlap integral involving Hermite
polynomials and Tom Koornwinder posted a response.
As announced in OP-SF NET 4.6, Topic #27, opsftalk, a discussion forum in
orthogonal polynomials and special functions, is now open for business. To

Topic #8 ------------- OP-SF NET 5.2 ------------ March 15, 1998

From: Arnold Nikiforov
Subject: Memorial Note about Vasily Borisovich Uvarov (1929 - 1997)
(This item appeared in our Activity Group's Newsletter, vol 8, no 2,
February 1998, p. 3)
The distinguished Russian mathematician and physicist Vasily Borisovich
Uvarov died on 23rd of September 1997, four days after his 68th birthday.
A flamboyant personality of splendid health, he suddenly contracted
Alzheimer's disease about 5 years ago, but died in hospital from
pneumonia.
Born into an old and cultivated Muscovite family, he graduated cum
laude in 1952 from the Physics Department of Moscow State University. For
the rest of his life, he worked at the M. V. Keldysh Institute of Applied
Mathematics. During his last years he was head researcher at the
Institute and professor at MSU.
When starting his work at the Institute, Uvarov entered the
Ippolitov-Ivanov Moscow Musical School as a student of violin and soon
graduated from the School. He played the violin throughout his life. As a
joke he used to say that, playing the violin, he could compete with
Einstein.
Research in the domain of high-temperature plasma physics (to be more
exact, in domain of quantum statistical models and interaction of
radiation with matter), started in the late 1950s. At that time computers
were only at the very beginning of their development, so the researcher
had to know how to obtain analytical solutions of rather complicated sets
of differential equations and, more specifically, had to be proficient in
the art of dealing with many special functions. Full control both of
analytical and difference methods enabled Uvarov to solve the problem of
photon absorption in spectral lines of many-electron atoms. In 1962 V.B.
Uvarov received the country's highest scientific award - the Lenin prize.
Later, Uvarov and Nikiforov developed a new approach to the theory of
special functions using a generalization of the Rodrigues formula. They
succeeded in obtaining, in the form of a Cauchy integral, a unified
integral representation for functions of hypergeometric type (1974). The
later book "Special Functions of Mathematical Physics" was based on these
ideas and went through several editions in Russian, French and English.
The latest edition was translated into English by the famous American
mathematician Ralph Boas (1988).
In 1983 it came to be recognized that along with the differential
equation of hypergeometric type one has to introduce the difference
equation of hypergeometric type over nonuniform lattices for many
functions, given on discrete sets of argument values. The polynomial
solutions of this equation (so-called q-polynomials) were obtained,
investigated and classified in collaboration with A.F. Nikiforov and S.K.
Suslov in the book "Classical Orthogonal Polynomials of a Discrete
Variable" (Moscow, Nauka, 1985; Springer-Verlag, 1991). This plan has
been carried out independently by the American mathematicians R. Askey
and J.A. Wilson.
Many-sidedly talented and wonderfully modest, sometimes unyielding, -
this is how Vasily Borisovich Uvarov will stay in our memory.

Subject: Review of book on Elliptic Functions
(This item appeared in our Activity Group's Newsletter, vol 8, no 2,
February 1998, p. 15)
Elliptic Functions. A Constructive Approach
By Peter L. Walker
Wiley, Chichester-New York-Brisbane-Toronto--Singapore, 214 pp., 1996,
ISBN 0-471-96531-6
This is a very remarkable book in which the theory of elliptic, i.e.
doubly-periodic, functions is completely developed by direct manipulations
of series, products and integrals. Hence the author takes a rather
algebraical point of view which is primarily stimulated by Eisenstein's
work.
Furthermore, to give a unified treatment, the author develops the theory
of circular and related functions (like gamma) by the same method.
Indeed, the starting point for the circular and related functions are the
families of series (k in Z, k > 0)
sum {n = -infty to infty} (x+n)^(-k) (1)
and
sum {n = 0 to infty} (x+n)^(-k), (2)
whereas the corresponding starting point for the elliptic functions is
given by the family of double series (k in Z, k > 0, Im tau > 0)
sum{n=-infty to infty} sum {m=-infty to infty} (x + m +n tau)^(-k). (3)
Contents:
0. Preliminaries: Here a short introduction to series, products, and
integrals is given.
1. Circular Functions: Starting with (1), the cotangent function, pi and
finally the other circular functions and their properties are developed.
2. Gamma and Related Functions: Using (2) instead of (1) yields the
gamma and related functions.
3. Basic Elliptic Functions: Starting from (3), the Weierstrass elliptic
functions are developed.
4. Theta Functions: Series similar to (3), e.g. with alternating sign, for
k = 1 lead to the Jacobian theta functions.
5. Jacobian Functions: The Jacobian elliptic functions are ratios of
Jacobian theta functions, and come next.
6. Elliptic Integrals: Elliptic integrals as inverses of elliptic functions
are discussed now.
7. Modular Functions: Here, modular functions are treated. These are
functions depending on the period ratio tau.
8. Applications: The use of elliptic functions in connection with waves,
number theory and elliptic curves are discussed.
References
Index
I am very impressed by the author's treatment. It is rather striking how
1. the theories of the circular and the elliptic functions can be
developed in much the same manner;
2. these developments can be done in such an algebraic way.
I recommend this book warmly to everybody who is interested in looking
"behind the scenes" of elliptic functions.

Subject: Review of book on Combinatorics
(This item appeared in our Activity Group's Newsletter, vol 8, no 2,
February 1998, pp. 15-16)
Introduction to Combinatorics
By Martin J. Erickson
Wiley, Chichester-New York-Brisbane-Toronto-Singapore, xii + 195 pp.,
1996,
ISBN 0-471-15408-3
This is a book of eleven chapters introducing itself as a textbook. This
review is written mainly from the point of view of evaluating it as such.
This reviewer admits to preferring textbooks to be systematic and
comprehensive. Some chapters of the present work tend to be sketchy rather
than systematic. We begin with a description of the contents.
Chapter 1 is a collection of needed information about sets, group theory,
linear algebra, and algebraic number theory. Sometimes the text can not
quite decide between just stating facts with reference to well-known
textbooks and actually giving definitions and some proofs. Some definitions
should have been avoided: what does it gain to define a finite set as one
having finitely many elements without defining "finitely" (or discussing
bijections involving the basic sets {1,2,3,...,n})? In the rather
important paragraph introducing the symmetric group the example of the cycle
decomposition has the element "3" appearing in two cycles (one assumes
that the second occurrence should have been "5", but this makes it
difficult for a student to understand the concept). The standard binomial
coefficient identities, like the Vandermonde sum, appear in this chapter,
but the proofs tend to be too swift for a beginner and uninteresting for an
expert.
Chapter 2 deals with the pigeonhole principle, has lots of detail and
presents interesting examples, like good approximation to irrational numbers
by rational ones. There is a brief introduction to graph theory (but it
refers to planar graphs without giving a definition, except later in one of
the problems).
Sequences and partial orders are taken up in Chapter 3. The author
displays more enthusiasm for the material here, which includes the
Erdos-Szekeres and Sperner theorems. The proofs are complete but place
some demands on the reader, like making a sketch or supplying more detail.
This style holds throughout the book. Chapter 4 continues with the theme
of existence theorems and takes up the topic of Ramsey numbers, graph
colorings, probabilistic methods and van der Waerden's theorem on
arithmetic progressions. These three chapters form the "existence" part.
The part on "enumeration" comprises Chapters 5 through 8. Counting
problems are introduced mostly using function concepts like injections and
surjections. The standard topics of Stirling numbers, Bell numbers,
derangements and their generating functions are covered here. The
unpleasant notation [x]^n is used for the Pochhammer symbol (x)_n. In six
pages, Chapter 7 discusses tableaux, hook-length formulas, and the
Robinson-Schensted correspondence. This seems rather sketchy and may not
be useful. On the other hand, Chapter 8 is a very good presentation of
Polya's theory of counting, with examples from graphs and cycle indices of
permutations.
The third part of the book on "construction" comprises Chapters 9, 10 and
11, and presents linear codes, Hamming and Golay codes, t-designs, Latin
squares, Hadamard matrices and the Leech lattice.
There is a bibliography of some sixty monographs and a six-page index. Also
there are statements of open problems (most of them have been open for some
time!) and selections of problems from past Putnam Competition Examinations.
As a textbook this work might be appropriate for an undergraduate seminar
for upper level mathematics students or as a supplement in a graduate
course. The coverage of Ramsey theory, Polya's counting methods, codes
and designs may be the strongest part of the book. Generally the proofs
demand careful perusal by the reader and have more words than formulas;
nevertheless the words are used very concisely! Every chapter has a section
of problems, which tend to be difficult. Somehow the reader is left with the
feeling of having been on a hasty tour of combinatorics without a
satisfactory amount of detail in the reader's favorite part of the subject
(whatever that might be). Indeed, similarly styled books have been
designated as "essays", indicating a collection of personal insights and
commentaries. This may be the better way of appreciating the present work.
