Subject: Jack Herriot

Jack Herriot, one of the founders of the CS department at Stanford,
passed away on Sunday, March 16, 2003. He was 87 years old.
"He was responsible for bringing George Forsythe to Stanford.
After Forsythe's death, he was acting chairman of the CS department.
He was a quiet man but very friendly and supportive." Gene Golub.

Herriot and Forsythe supervised three NA PhD's: Paul Richman, David
Stoutemyr, and Michael Malcolm.

The services for Jack Herriot will be held at 3:30 p.m. on Saturday,
April 26 at the First United Methodist Church, 625 Hamilton Ave (at
Webster St.) in Palo Alto.

Subject: Conjugate Gradients in Function Spaces

Is anything known about the convergence of the conjugate
gradient method for linear equations in function spaces?

E.g., is it convergent for a linear system Ax=b if A is
self-adjoint, positive definite, and 1-A is compact?
What about the rate of convergence?

Subject: Matrix Systems of Differential Equations

Dear NA Digest readers:

In the discretization of the problem I'm studying I get a matricial system of
differential equations in the form:

dX/dt = A X B

where A and B are square matrices. I'm sure these problems appear in lots of
fields of interest, but I've been unable to find any information about their
solution. Could anybody tell me which would be the (matricial) solution of
these problems, or how can it be approximated? Comments with references to
fields where these equations are common will also be specially helpful.

Best regards.

Subject: New Book, Finite Element Analysis of Shells - Fundamentals

"The Finite Element Analysis of Shells - Fundamentals"
A new book by D. Chapelle (INRIA-Rocquencourt, France) and K.J. Bathe
Springer, 2003, 330p, ISBN: 3-540-41339-1

This book presents a modern continuum mechanics and mathematical
framework to study shell physical behaviors, and to formulate and
evaluate finite element procedures. With a view towards the synergy that
results from physical and mathematical understanding, the book focuses
on the fundamentals of shell theories, their mathematical bases and
finite element discretizations. The complexity of the physical behaviors
of shells is analysed, and the difficulties to obtain uniformly optimal
finite element procedures are identified and studied. Some modern finite
element methods are presented for linear and nonlinear analyses.

Subject: Conference in Greece on Computional Methods


Kastoria, Greece
September 12-16, 2003 or

In the past decades many significant insights have been made in several
areas of Computational Methods in Sciences and
Engineering. New problems and methologies have appeared. There is
permanently a need in these fields for the advancement
of information exchange. This undoubtedly beneficial practice of
interdisciplinary and multidisciplinary interactions should
be expressed by an interdisciplinary and multidisciplinary conference on
Computational Methods in Sciences and Engineering.
ICCMSE 2003 aims at playing the above role and for this reason the aim
of the conference is to bring together computational
scientists and engineers from several disciplines in order to share
methods, methologies and ideas.

The topics to be covered include (but are not limited to):
Computational mathematics, Computational physics,
Computational chemistry, Computational engineering, Computational
mechanics, Computational finance, Computational
medicine, Computational biology, Computational economics, High
performance computing, Mathematical Methods in Sciences
and Engineering, Industrial Mathematics, etc.

Computational Modelling in Medicine
17-19 September 2003
Edinburgh, Scotland

(ICMS), and incorporating the twelfth Scottish Computational Mathematics
Symposium (SCMS). The meeting is supported by EPSRC and LMS. The first day
will follow the usual SCMS format of five invited lectures, and the second
and third days will involve a mixture of invited and contributed talks.


Mathematical modelling and numerical simulation play a major role in many
important medical applications. The meeting will be organised around the
two interlinked themes of THE VASCULAR AND PULMONARY SYSTEMS and SOFT
TISSUE MECHANICS. The purpose is to bring together people who work on
mathematical modelling, numerical analysis, simulation and direct medical
applications related to these areas, and to act as a focus to stimulate
further research and development of even more realistic medical
