Topic #1  -----------  OP-SF NET 10.5 ------------ September 15, 2003

                       ~~~~~~~~~~~~~~

From: OP-SF NET Editor muldoon@yorku.ca 

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: 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.

From: OP-SF NET Editor muldoon@yorku.ca

Subject: About the Activity Group

 

The SIAM Activity Group on Orthogonal Polynomials and Special Functions

consists of a broad set of mathematicians, both pure and applied.  The

Group also includes engineers and scientists, students as well as

experts. We have around 140 members scattered about in more than 20

countries. Whatever your specialty might be, we welcome your

participation in this classical, and yet modern, topic.  Our WWW home

page is:

 

  http://math.nist.gov/opsf/

 

This is a convenient point of entry to all the services provided by the

Group.  Our Webmaster is Bonita Saunders (bonita.saunders@nist.gov).

 

The Activity Group sponsors OP-SF NET, which is transmitted

periodically by SIAM.  It is provided as a free public service;

membership in SIAM is not required.  The OP-SF Net Editor is Martin

Muldoon (muldoon@yorku.ca).

 

To receive the OP-SF NET, send your name and email address to

poly-request@siam.org.

 

Back issues can be obtained at the WWW addresses:

The NET provides fast turnaround compared to the printed Newsletter,

also sponsored by the Activity Group, and edited by Rafael Yanez.  It

appears three times a year and is mailed by SIAM.  Back issues are

accessible at:

 

http://www.mathematik.uni-kassel.de/~koepf/siam.html

 

To receive the Newsletter, you must be a member of SIAM and of the

Activity Group.  SIAM has several categories of membership, including

low-cost categories for students and residents of developing countries.
