Subject: Kermit Sigmon
Kermit Sigmon, 1936-1997
Kermit Sigmon succumbed to liver cancer on January 14, 1997, after being
ill only one month. He is survived by two sisters, his wife Ruth, daughter
Kristina, and two grandchildren. His many friends, colleagues and
students will greatly miss his cheerful and congenial company, generous
spirit, clearheaded leadership and outstanding teaching.
He received his Ph.D. from the University of Florida in 1966, working in
topological algebra under the direction of Alexander Doniphan Wallace. He
joined the faculty at Florida and remained there except for several summer
consulting positions and sabbatical years elsewhere.
Kermit directed three Ph.D. theses and published 14 papers on topics in
functional equations and Alexander cohomology. Over time his interests
shifted and he wrote several papers in numerical linear algebra as well
as a well known handbook, MATLAB Primer, published by CRC Press. He was
an Associate Editor for Aequationes Mathematicae (1974-1980) and SIMAX
(1989-present). He held a variety of offices in the Florida Section of
the MAA and also supported the training of math teachers.
He was a demanding but very popular teacher at Florida and won several
teaching awards. Most recently he was selected in 1995 by the Department of
Mathematics for Teaching Incentive Program award, which is given for
teaching excellence and provides a substantial salary increase. He also
won a University of Florida Teaching Award for the 95/96 academic year.
Kermit was one of the leaders of the ATLAST Project. He served
on the original planning team for the ATLAST workshops. During the period
1992-95 he served as presenter for three workshops and did an outstanding job.
ATLAST is an NSF-funded project which began in 1992 and has provided 16
workshops around the U.S. to date; the purpose of these is to encourage
and facilitate the use of software in teaching linear algebra and
to assist college faculty to update their linear algebra courses.
Throughout his career Kermit has made many invaluable contributions
to his department, including serving as Associate Chair, Undergraduate
Coordinator, Faculty Mentor for minority students, and providing academic
advising for hundreds of students. His work on curriculum development
has been substantial. He has even written software to facilitate the
department's record-keeping.
Kermit was an avid biker and tennis player, and his enthusiasm for biking is
probably what got him on the Metropolitan Planning Commission for Alachua
County and kept him there for 20 years. He also served on the University's
Transportation Committee, which developed a Master Plan for cooperation
between the university, city and county to expand local bus service and
make Gainesville a more biker-friendly city. These contributions led to
a number of recognitions, including the Gainesille City Commission
proclaiming August 5, 1985 to be "Kermit Sigmon Day".
Contributions may be made to the American Cancer Society or the the League
of American Bicyclists, 190 W. Ostend St., Suite 120, Baltimore, MD 21230,

Hello
I'm interested in online resources to assist in the teaching of (undergraduate)
numerical analysis. Does anyone know of ay mailing lists where such a discussion
could occur? If people do NOT know of one, would they be interested in joining
one? I have the capability on my machine, abacus.oxy.edu, to host a mailing list
and would be delighted to setup one, called NA-TEACH or something. If I get
between 5 and ten responses to this message I will interpret that as a gauge
that there IS enough interest to maintain a mailing list on the teaching of
numerical analysis.
Thanks...

various a posteriori error estimators (residual, local Dirichlet and
Neumann problems, hierarchical bases, averaging) are presented and compared
for the Laplace equation as a model problem. Chapter II gives an abstract
framework for (non-) linear problems which is applied in Chapter III to
quasi-linear elliptic pdes of 2nd order, the stationary Navier-Stokes
equations, elasticity, the biharmonic equation and eigenvalue problems.
Chapter IV gives an introduction to adaptive mesh-refinement techniques and
the relevant data structures.

This book contains articles corresponding to some of the
talks delivered at the Foundations of Computational
Mathematics (FoCM) conference at IMPA in Rio de Janeiro in
January 1997. FoCM brings together a novel constellation of
subjects in which the computational process itself and the
foundational mathematical underpinnings of algorithms are
the objects of study. The conference was organized around
nine workshops: systems of algebraic equations and
computational algebraic geometry, homotopy methods and real
machines, information based complexity, numerical linear
algebra, approximation and PDE's, optimization, differential
equations and dynamical systems, relations to computer
science and vision and related computational tools. The book
gives the reader an idea of the state of the art in this
emerging discipline.

Subject: Re: A Problem Involving Positive Matrices
In NA-digest v96n47, December 16, 1996, Avi Vardi asked about the existence and
uniqueness of a solution $x$ to $e^T x = 0$, $c(x) - B(x)x = 0$, where $e$ is
the vector of ones, $c(x)$ is a vector and $B(x)$ a symmetric matrix depending
(discontinuously) on $x$ and on a positive matrix $A$.
It turns out that a reformulation of this problem allows an easy solution.
Indeed, one can show that
\[
[c(x) - B(x)x]_i = \sum_h [a_{hi}(x_i - x_h + 1)_+ - a_{ih}(x_h - x_i + 1)_+],
\]
where $\lambda_+$ denotes $\max\{\lambda, 0\}$, which shows that
$c(x) - B(x)x$ is indeed continuous, and in fact is the gradient
of the function
\[
f(x) := \sum{h,i} a_{hi}(x_i - x_h + 1)_+^2.
\]
The existence and uniqueness now easily follow since $f$ is strictly convex
on $X := \{x: e^T x = 0\}$ and $\{x \in X: f(x) \leq f(0)\}$ is compact.
The problem arises in ranking teams or players based on their records.

Subject: New Codes for Stiff Two-Point Boundary Value Problems
This is to announce two new codes, ACDC.f and COLMOD.f, for
the solution of singularly perturbed two-point boundary value
problems. These are extensions of the NETLIB codes TWPBVP.f and
COLNEW.f, and are designed to solve stiff boundary value problems
in an efficient way. The code ACDC.f is a deferred correction code
based on Lobatto Runge-Kutta formulae while the code COLMOD.f is a
modification of the collocation code COLNEW. Both codes are set in
an automatic continuation framework to allow extremely stiff problems
to be solved efficiently. The codes can be accessed from NETLIB under
the directory ode.
Extensive results comparing these new codes with some existing
NETLIB codes, together with double precision versions of ACDC.f and
COLMOD.f are on the Imperial College web page. This can be accessed at

Subject: Optimization Code Available
The optimization code conmax.f is now available in netlib/opt/
Abstract
A Fortran program is now available to solve the following general
nonlinearly constrained optimization problem:
Choose x1,...,xn to minimize w subject to
abs(fi - gi(x1,...,xn)) .LE. w, 1 .LE. i .LE. m1
gi(x1,...,xn) .LE. w, m1 + 1 .LE. i .LE. m2
gi(x1,...,xn) .LE. 0, m2 + 1 .LE. i .LE. m3
where m1, m2, m3 are integers with 0 .LE. m1 .LE. m2 .LE. m3, the fi are
given real numbers, and the gi are given smooth functions. Constraints
of the form gi(x1,...,xn) = 0 can also be handled without problem. Each
iteration of our algorithm involves approximately solving a certain
nonlinear system of first order ordinary differential equations to get a
search direction for a line search and using a Newton-like approach to
correct back into the feasible region when necessary. Our experience to
date has been that the program is more robust than any of the library
routines we have tried, although it generally requires more computer time.
We have found this program to be an extremely useful tool in diverse
areas, including polymer rheology, computer vision, and computation of
convexity-preserving rational splines. The package contains an SLP
routine as a backup, as well as user-callable subroutines for Muller's
method real root finding, line search, free-variable LP, and least-
distance QP. The program and its extensive user's guide can be obtained
by sending the message send conmax from opt to netlib@ornl.gov. For a
discussion of the algorithm, program, and experimental results, please

BLAS TECHNICAL FORUM, February 27-28, 1997, Dallas, TX
We are planning a BLAS Technical Forum meeting on February 27-28.
The meeting will be hosted by Hsin-Ying Lin of HP/Convex and the
meeting will be held at the Clarion Hotel in Dallas, TX (a couple
of miles from HP):
Clarion Hotel
1981 North Central Expressway
Richardson, TX 75080
(800) 285-3434
The Forum has been established to consider expanding the Basic Linear
Algebra Subprograms (BLAS) in a number of directions in the light of
modern software, language, and hardware developments. The first meeting
of the Forum was held in Nashville on February 19-20, 1996 and the
previous meeting was in Eagan, MN on November 7-8, 1996.
Working groups have been established to consider the overall
functionality, possible extensions, and a lightweight interface
for the BLAS, as well as the short term goals of the forum. Other
subgroups have also been established, either to advise the current
working groups or as placeholders for future working groups on parallel
processing issues, sparse operations, and language binding issues.
We strongly urge and encourage attendance at the meeting
so that we can make tangible progress towards much needed standards.
Wide input is needed to help ensure that emerging proposals are useful
and acceptable to the community.
It is appreciated that it is not easy for everyone to attend the
meetings of the Forum, but we would nevertheless welcome your input
since we wish the discussion to be as open as possible, and the results
to reflect consensus from the community at large.
Please send us items you would like to see on the agenda
or that you would like to discuss.
We will plan to start the meeting with lunch at 12:00 pm on Thursday,
February 27th and end by mid-afternoon on Friday, February 28th. Lunch is
provided on site both days.

Subject: Postdoctoral Position at Massey University
Mathematics Department, Massey University, Palmerston North, New Zealand
THE PROJECT
"Unconventional methods and structures in numerical differential equations"
The project is to develop and explore existing and new methods for systems
with special properties such as symmetries, integrals, or preservation of
symplectic or volume structures, methods which offer improved long-time
performance and which shed light on the foundations of numerical analysis.
THE POSITION
The project is funded by a research grant from the Marden Fund of New Zealand.
The appointment is to commence as soon as possible and will be offered for
a term of up to three years. To apply you should have completed, or expect
to soon complete, a Ph.D. in mathematics or a related discipline, and have
a good record of independent publication in your field. A background in
numerical differential equations, dynamical systems, differential geometry
or complexity theory would be desirable: the project can flex to suit your
experience.
