Topic #1 ----------- OP-SF NET 10.5 ------------ September 15, 2003
~~~~~~~~~~~~~~
From: OP-SF NET Editor
Subject: Joaquin Bustoz 1939-2003
His many friends and collaborators in the OP-SF community are saddened by
news of the passing on August 13, 2003 of Joaquin Bustoz, Professor of
Mathematics at Arizona State University (ASU). His death was the result of
injuries received in a car accident on July 6.
Joaquin did his degrees at ASU and spent much of his career there, but
also worked at other places notably the University of Cincinnati. A period
at Universidad Nacional de Colombia led to the joint publication of a
booklet in Spanish on Fourier Series with Jairo Charris whose untimely
death was reported in our July 15 issue.
Joaquin's early work was in summability theory and approximation theory
with later contributions to inequalities for special functions, q-analogs,
sieved orthogonal polynomials, Turan inequalities and basic analogs of
Fourier series, among other things.
Joaquin Bustoz served as Chair of his Department at Arizona State and was
very successful in mentoring activities for minority students. He received
at least two major national awards for this activity. He was one of the
organizers of the NATO Advanced Study Institute on Special Functions, held
at ASU. His accident came only about a week before our Activity Group's
Summer School in Coimbra, Portugal where he was scheduled to be one of the
principal lecturers.

Subject: Georgia Tech: Constructive Functions Tech-04
FIRST ANNOUNCEMENT: CONSTRUCTIVE FUNCTIONS TECH-O4
An International Conference
Georgia Institute of Technology, Atlanta, GA
November 7-9, 2004
This conference, honoring the 60th birthday of Ed Saff, will be an
international conference covering all aspects of constructive function
theory, potential theory and approximation theory. Ed Saff has played a key
role in building scientific cooperation between mathematicians of many
nations. Accordingly, the conference aims to attract mathematicians from
all around the world, especially young graduate mathematicians and graduate
students.
Georgia Tech is conveniently located in Atlanta, close to the subway, and
just a subway ride from Atlanta's Hartsfield International Airport. The
latter is the hub of Delta, and an ideal entry into the United States.
Early November in Atlanta sees the tail end of Fall, and the weather is
mild and pleasant. If you are interested in attending, please visit our
website and fill in the online preliminary registration form. The main page
is at:
www.math.gatech.edu/news/conferences/at04/
Registration is at:

Subject: Lee Lorch honoured by ISAAC
Lee Lorch (York University) was appointed an Honorary Member Life of ISAAC
(International Society for Analysis, its Applications and Computation) by
decision of the ISAAC Board at its recent meeting in Toronto. He was
presented with this honour by ISAAC President Heinrich Begehr (Freie
Universität Berlin) at the closing ceremony of the ISAAC 2003 Congress held
at York University, Toronto, August 11-16, 2003. A citation read by
Victor Burenkov (Cardiff University) referred to Lorch's contributions to
real analysis, special functions, ordinary differential equations,
summability theory, approximation theory and Fourier analysis, his
struggles on behalf of the disadvantaged and his continuing efforts for
world peace and understanding between peoples.
Founded by Robert P. Gilbert in 1994, (ISAAC) is a non-profit organization
to promote and advance analysis, its applications, and its interaction with
computation. See the ISAAC web site at

Subject: Call for Submissions - SIAM Student Paper Prize
CALL FOR SUBMISSIONS
for
SIAM Student Paper Prize
The 2004 SIAM STUDENT PAPER PRIZE will be presented at the 2004 SIAM Annual
Meeting scheduled for July 12-16, 2004, in Portland, Oregon.
-Principal Guidelines-
The SIAM Student Paper Prize is awarded every year to the student author(s)
of the most outstanding papers submitted to the SIAM Student Paper
Competition. This award is based solely on the merit and content of the
student's contribution to the submitted paper. Up to three papers will be
selected for the prizes.
The purpose of the Student Paper Prize is to recognize outstanding
scholarship by students in applied mathematics and scientific computing.
-Selection Procedures-
Eligibility is restricted to students in good standing who have not
received their Ph.D. as of January 1 of the year in which the prizes are
awarded.
Submissions may be based on co-authored papers, provided that the student's
advisor will attest that the student's work played a pivotal role in the
results. A letter from the student's advisor or department chair must
accompany each entry to verify these conditions.
To enter the competition, a student must submit: (1) an extended abstract,
in English, of a paper, and (2) a short biography. The total length of the
submitted abstract (including bibliography) may not exceed five pages.
The student also must submit (3) the complete paper, which will be used for
clarification of any questions the committee may have about the extended
abstract. In addition, the student's advisor or an interested faculty
member must submit (4) a letter describing and evaluating the paper's
contribution to the literature and the student's role in the scholarship.
-Deadline for Submissions-
All papers and accompanying documentation must be received at the SIAM
office by February 13, 2004.
-Notification of Prize Winners-
The SIAM President will notify the recipient(s) at least six weeks before
the award date.
Each recipient is required to present his or her paper at the meeting where
the prize(s) are awarded. If attending the meeting poses a serious
hardship, an exception may be granted by the SIAM President.
-Description of the Award-
Each recipient of the SIAM Student Paper Prize shall receive a framed
certificate and a cash award of $1,000. Winners also receive $500 toward
travel expenses and gratis registration for the meeting.

This project is developing second-generation capabilities for two
mathematical digital collections that support mathematics, engineering,
physics, and applied sciences education and research: the "MathWorld" and
the "Functions" sites at Wolfram Research. Functional enhancements are
being added to these sites, and collection and item-level metadata from
these resources are being integrated into the NSDL Metadata Repository
framework via maintenance of an Open Archives Initiative (OAI) server.
Topic #9 ----------- OP-SF NET 10.5 ------------ September 15, 2003
~~~~~~~~~~~~~~
From: Tom Koornwinder
Subject: New paper on matrix-valued hypergeometric functions
Juan A. Tirao,
The matrix-valued hypergeometric equation,
Proceedings National Academy of Sciences 100 (2003), no.14, pp. 8138-8141
(not on arXiv, not yet in MathSciNet)
http://www.pnas.org/content/vol100/issue14/index.shtml#MATHEMATICS
Abstract:
The hypergeometric differential equation was found by Euler [Euler, L.
(1769) Opera Omnia Ser. 1, 1113] and was extensively studied by Gauss
[Gauss, C. F. (1812) Comm. Soc. Reg. Sci. II 3, 123162], Kummer [Kummer,
E. J. (1836) Reine Ang. Math. 15, 3983; Kummer, E. J. (1836) Reine Ang.
Math. 15, 127172], and Riemann [Riemann, B. (1857) K. Gess. Wiss. 7,
124]. The hypergeometric function known also as Gauss' function is the
unique solution of the hypergeometric equation analytic at z = 0 and with
value 1 at z = 0. This function, because of its remarkable properties, has
been used for centuries in the whole subject of special functions. In this
article we give a matrix-valued analog of the hypergeometric differential
equation and of Gauss' function. One can only speculate that many of the
connections that made Gauss' function a vital part of mathematics at the
end of the 20th century will be shared by its matrix-valued version,
discussed here.
