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,

**Subject: Mailing List for the Teaching of Numerical Analysis**

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...

This book gives an introduction to a posteriori error estimation and

adaptive mesh-refinement techniques for elliptic pdes. In Chapter I,

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

http://www.ma.ic.ac.uk/~jcash/BVP_software/readme.html

**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.

Mathematical Sciences, to be held from 1st October 1997 or as soon as possible

after that date. The Department of Mathematical Sciences has active research

groups in Pure Mathematics, Mathematical Physics, Numerical Analysis and

Statistics, and is committed to excellence in both research and teaching. Pure

Mathematics and Applied Mathematics (Mathematical Physics and Numerical

Analysis) were each graded 5 in the recent Research Assessment Exercise.

It is expected that the appointments will be made in the areas of Pure and

Applied Mathematics, with at least one in each area. Salaries are likely to

be on the Lecturer A scale ( 15,154 - 19,848 pounds p.a.).

**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.
