Subject: Minisymposium on "Handbooks for Special Functions and the
                             World Wide Web"

The minisymposium will be held at the July 14-18 1997 SIAM Annual Meeting
in Stanford as an initiative of the SIAM Activity Group on Orthogonal
Polynomials and Special Functions.  Dick Askey and Willard Miller are
co-organizers. The principal handbooks on special functions, the "Bateman
Project" and the NIST "Handbook of Mathematical Functions" are among the
most useful, widely consulted technical volumes ever published, but they
are now out of date, due to rapid research progress and to revolutionary
changes in technology. The Minisymposium will feature talks by
representatives of the groups that are proposing to update the Bateman
Project and Abramowitz & Stegun, respectively, and talks with critiques of
those CD-Rom and WWW handbook projects that are already available. The
Minisymposium will conclude with a general discussion concerning the
appropriate format and structure for handbook projects, and funding
possibilities.  The speakers will include Mourad Ismail, Dan Lozier and
Dick Askey, among others.

Subject: First ISAAC Conference, Delaware, June 1997

Dear Colleagues:

As you already know (see OP-SF Net 3.5, Topic #3), I am organizing Session
13 on "Orthogonal Polynomials"  at the First ISAAC Conference, University
of Delaware, Newark, Delaware, June 3-7, 1997. Note that the conference is
scheduled one day later than originally stated to enable the participants
to get cheap flights. The emphasis of this session will be on the use of
symbolic computation in connection with orthogonal polynomials and special
functions. It is the purpose of the proposed section to bring together
developers of symbolic algorithms and implementations which are connected
with orthogonal polynomials and special functions with users of computer
algebra systems who need this type of software.

Topic #3  --------------  OP-SF NET 4.1 --------------- January 15, 1997
From: Rudolf Gorenflo <gorenflo@math.fu-berlin.de>
Subject: Report on Second International Workshop Transform Methods &
    Special Functions: Varna, Bulgaria, August 23-30, 1996

The following report appeared in our October 1996 printed Newsletter.

This workshop, whose scientific program lasted from August
24 to August 29, 1996, was organized by:

  1. Institute of Mathematics and Informatics of the Bulgarian Academy of
       Sciences;

  2. Institute of Applied Mathematics and Computer Sciences of Technical
       University Sofia;

  3. Union of Bulgarian Mathematicians;

  4. Union of Scientists in Bulgaria;

  5. Istituto per la Ricerca di Base (Monteroduni, Italy).

It took place in the hotels Magnolia and Detelina, north of Varna, with a
wide view of the Black Sea. It was dedicated to the 100th anniversary of
the birth of the Bulgarian mathematician Academician Nikola Obrechkoff
(1896-1963, born in Varna) who did pioneering work in such diverse fields
as analysis, algebra, number theory, numerical analysis, summation of
divergent series, probability and statistics.  The workshop was attended
by more than seventy participants from twenty countries, alphabetically
from Australia to Vietnam, the largest groups coming from Poland (20),
Bulgaria (12) and Japan (7).

After the opening ceremonies (which included a greeting speech from
Varna's Mayor and an appreciation of Obrechkoff and his achievements by
I. Dimovski (Sofia) the series of lectures commenced with a plenary
lecture by Prof. E.R. Love from Melbourne (Australia), the oldest
participant at the Conference, on his joint work with M.N. Hunter on
"Expansions in series of Legendre functions".

In total there were six plenary lectures, presented by E.R. Love (title
already mentioned), F. Mainardi (Bologna, Italy) on "Applications of
fractional calculus in mechanics", R. Gorenflo (Berlin, Germany) on "The
tomato salad problem in spherical stereology", P.G. Rooney (Toronto,
Canada) on "The ranges of Mellin multiplier transformations",
H.M. Srivastava (Victoria, Canada) on "Some operational techniques in the
theory of special functions", and Vu Kim Tuan (Kuwait) on "Integral
transforms and supports of functions". Then 63 lectures were presented in
(up to three)  parallel sessions with headings "Integral Transforms and
Special Functions", "Fractional Calculus", "Special Functions",
"Geometric Theory of Functions", "Differential Equations", "Integral
Transforms & Operational Calculi", "Mathematical Analysis and
Applications", "Integral Transforms", "Varia". In addition, in the
closing session P. Rusev, I. Dimovski and V. Kiryakova lectured on
"Obrechkoff's generalization of Descartes' rule" and "Obrechkoff's
integral transforms".

The conference ended with a final ceremony in which P. Antosik (Katowice,
Poland) distributed prizes (to the three largest delegations) and praise
(to individuals).

In the lectures, besides some educational reviews, many new research
results were presented. This reporter, due to the multiple sessions, could
not attend all the talks; however he feels it appropriate to mention three
of them he considered special highlights in that they gave impressive
recent results, obtained just in the few weeks preceding the conference.
They were two lectures by P.L. Butzer and S. Jansche (Aachen, Germany) on
"The Mellin transform, finite Mellin transform and Mellin-Fourier
transform", "The Mellin-Poisson summation formula and the exponential
sampling theorem", and the plenary lecture by Vu Kim Tuan. In many
lectures the importance of special and of general types of special
functions for applications inside and outside of mathematics was stressed.
Particular mention should be made of hypergeometric functions and their
generalizations, H and G functions, confluent hypergeometric functions,
Bessel functions, Mittag-Leffler functions, and various types of
orthogonal polynomials.

The program also provided a two-hour plenary discussion on "Physical and
geometrical meanings and applications of fractional calculus operators"
that was well attended and opened stimulating aspects. Topics of
discussion were, among other things, some problems raised in
H.M. Srivastava's collection of "Open questions for further researches on
fractional calculus and its applications" (pp. 281-284 in K. Nishimoto,
ed., Fractional Calculus and its Applications, Nihon University, Tokyo
1990). In particular, arguments were exchanged on the question whether
there is a relationship between fractional calculus and fractal geometry
or whether the only relationship is the coincidence of the first five
characters of the words "fractional" and "fractal".  Fortunately, the
discussion did not stick to this problem.

The meeting was framed, thanks to the organizers P.  Rusev, I. Dimovski,
V.  Kiryakova, L. Boyadjiev (all from Sofia) and Sh. Kalla (Kuwait), by an
appealing social program (reception, on August 27 a whole-day excursion to
the old town Shumen, 100 km to the west of Varna, birth-place of Prof.
Rusev, and the fascinating surroundings of Shumen, with more than two
hours of Bulgarian folklore and after-lunch dancing, and on August 28 a
celebration of Prof. Rusev's 65th birthday).

Thanks to St. Peter Black Sea sunrises, beach, sand, sun and clear water
swimming could be enjoyed. The organizing committee did, in an admirable
manner, their best to smooth all the (in retrospect, few) problems that
are bound to arise in such a meeting.

The Workshop's Proceedings (like those of the preceding one held in
Bankya/Bulgaria, 12-17 August 1994) will be published by "Science Culture
Technology (SCT) Publishing" in Singapore.

Topic #5  --------------  OP-SF NET 4.1 --------------- January 15, 1997
From: OP-SF Net editor <thk@wins.uva.nl>
Subject: Steele Prize for Bruce Berndt

According to the Notices of the American Mathematical Society, November
1996, pp. 1340-1341, Bruce C. Berndt has received one of the three 1996
Steele Prizes.

Citation:

  The prize  was awarded to Bruce Berndt for his four volumes "Ramanujan's
  Notebooks", Parts I, II, II, and IV, Springer, 1985, 1989, 1991, and 1994.
  In recognition of Berndt's heroic and extraordinary achievement in
  exposing to the general mathematical researcher a trove of results
  that were utterly inaccessible before, the AMS decided this year,
  exceptionally, to broaden the standard interpretation of "exposition".
  In an impressive scholarly accomplishment, spread out over 20 years,
  Berndt has provided a readable and complete account of the Notebooks,
  making them accessible to other mathematicians. Ramanujan's enigmatic,
  unproved formulas are now readily available, together with context and
  explication, often after the most intense and clever research efforts on
  Berndt's part.

From: OP-SF Net editor <muldoon@yorku.ca>
Subject: Joaquin Bustoz receives Presidential Mentoring Award

Joaquin Bustoz, Arizona State University, was one of 16 recipients of the
first Presidential Awards for Excellence in Science, Mathematics and
Engineering Mentoring named by U.S. President Clinton on September 25,
1996.  The award recognizes their work in "encouraging minorities, women
and persons with disabilities to earn degrees in science, mathematics and
engineering"

The following information is taken from the December 1996 issue of FOCUS,
the Newsletter of the Mathematical Association of America: "Bustoz has
received numerous teaching awards, and his research has been in analysis,
focusing most recently on orthogonal polynomials and special functions.
Since 1985 Bustoz has been involved in enhancing the number and quality of
minority students entering the university and intending to study
mathematics and science.  He initiated and directs a Math-Science Honors
Program at ASU, which provides an intense introduction to university
mathematics to two hundred high school students each summer.  As a direct
result of the program, nearly one-third of ASU's mathematics majors are
from underrepresented minorities."

From: Tom Koornwinder <thk@wins.uva.nl>
Subject: Revising the 1991 Mathematics Subject Classification

See OP-SF Net 3.6, Topic #3. There was one further suggestion for revising
1991 Mathematics Subject Classification.
Per W. Karlsson <karlsson@mat.dtu.dk> wrote:

  In my opinion, 40A05 is too broad; there should be a separate box
  for multiple series. This, I think, goes for integrals too (40A10).

Several people pointed out that in a list distributed some years ago
by Zentralblatt, items  33C25 - 33C55  and  33D25 - 33D45 are at
variance with the AMS list. This seems to have been corrected later.



Topic #11  --------------  OP-SF NET 4.1 --------------- January 15, 1997
From: Hans Volkmer <volkmer@csd.uwm.edu>
Subject: Question about Heine polynomials

Dear Colleagues,

I'm currently working on the polynomials that are treated on pages
151-155 of Szego's book on orthogonal polynomials. I call them Heine
polynomials because they were first studied by Heine. They are called
Stieltjes polynomials in Morris Marden's book "Geometry of
Polynomials".  The treatment in Szego's book seems to be rather
incomplete. Is there literature on the Heine polynomials in the last
decades?

Your help would be very appreciated.
