Subject: Oved Shisha Injury

Dear Colleaques
Professor Oved Shisha of the University of Rhode Island was injured
in a traffic accident very seriously last Friday evening March 31-95
in Providence.As he was getting off the bus he was struck by a car.
Since then he is unconcious in a coma in the R.I.hospital in
Providence R.I.His situation is listed as very critical.

Let us everybody pray for him to survive. Oved had another bad accident
30 something years ago in Dayton Ohio and that time survived. I pray
that this happens again.

Professor Shisha is the main organiser of "Approximation Theory"in
the west as a separate field with his creation of "J.Approx.Th."
in 1968. He was also the founder of several subareas of A.T such as
"monotone approximation","Korovkin inequalities" etc,also he did
important work in integration theory.

If I have more news I let you know.

Sincerely yours
George Anastassiou
Professor of Mathematics
Univ.Memphis,Memphis,TN,USA

Subject: Svata Poljak

This message is to inform the community of the very sad news that Svata
Poljak was involved in a fatal car accident.
This occurred near Prague on Sunday April 2, 1995.

Svata recently relocated to University of Passau, in Passau, Germany.
(URL: http://www.fmi.uni-passau.de/~poljak/papers.html )
His main contributions are in combinatorics and combinatorial optimization.
He has important contributions in many areas including:
theory of matroids, matching theory, the max-cut and stable set problem;
spectral approaches to graph problems;
convex and polyhedral relaxations; semidefinite programming;
and various other integer programming related problems.
His early important work was related to systems in neural networks.

He has collaborated with many people. In particular, we can state from
personal experience that he was a rare person to collaborate
with, because of his exceptional
mathematical ability as well as his warm friendship.
The upcoming special issue in Mathematical Programming on Semidefinite
Programming will be devoted to his memory.

He is survived by his wife and two sons.
The funeral is in Prague this coming Monday.
Those wishing to send condolences to his wife Jana can do so at the
address in Prague:

Subject: Bau & Trefethen Linear Algebra Book

BAU AND TREFETHEN TEXT, "NUMERICAL LINEAR ALGEBRA"

We are in the process of completing a graduate textbook on
Numerical Linear Algebra. Our aims are beauty, depth of insight,
and brevity. The book is split into about 36 lectures, each
about 6 pages long. It is based on the course Trefethen has
taught repeatedly at MIT and Cornell during the past ten years.

We expect that it is likely the book will be published by SIAM
in 1996. Meanwhile, a preliminary version (not yet including
exercises) may be made available in summer 1995 for a few
people who wish to use the book in a course in fall 1995.
If you might be interested in this possibility, please take a
look at the table of contents and sample chapters available at
http://www.cs.cornell.edu/Info/People/lnt/lnt.html. Then please
contact us if you need further information.

Subject: Sign Pattern in a Matrix

In solving boundary value problems for Laplace's equation
in doubly connected regions, we get an nxn matrix with
the following sign pattern (for a 4x4 matrix)

+  +  +  +

-  +  +  +

+  -  +  +
