Subject: New Book, Optimal Solution of Nonlinear Equations

New book: Optimal Solution of Nonlinear Equations, K. Sikorski,
Oxford Press, 2001. (ISBN 0-19-510690-3)


The purpose of this monograph is to provide an overview of optimal
computational methods for the solution of nonlinear
equations, fixed points of contractive and noncontractive
mappings, and for the computation of the topological degree.
We analyze the worst case scenario here. This means that for
a given error criterion and a tolerance $\e$, the methods
guarantee the computation of an $\e$-approximation to the solution
for every function in a given class $F$. Optimal
methods solve the problem in the smallest possible time.

We study several classes of functions, with special emphasis
on tight complexity bounds and methods that are close to or
achieve these bounds. In addition, pseudocodes and numerical tests
of several methods are exhibited.

Subject: Industrial Mathematics Modeling Workshop at NC State

2001 Industrial Mathematics Modeling Workshop for
Graduate Students
July 23-July 31, 2001
Center for Research in Scientific Computation
North Carolina State University


Expose 36 graduate students in mathematics to challenging
and exciting real-world problems arising in industrial
and government laboratory research

Introduce students to the team approach to problem solving


This workshop will be the 7th one of this type to be held at NCSU.
We offer the support of experienced faculty and staff as well as
extensive financial support (local living expenses and allocation
for travel) to all selected students who are U.S. citizens or permanent
residents. The workshop is supported by the National Science


The students are divided into six-member teams to collaborate on
industrial mathematics projects presented by experienced scientists
and enginners. The corresponding problems are not the kind of
academic exercises often considered in classrooms. The challenges
they raise typically require fresh new insight for both formulation
and solution. During the workshop, each group is mentored by both
the problem presenter and a faculty adviser.


Boeing: unregistered laminographic reconstruction.
Centura Banks, Inc.: interest rate models and new type of derivatives.
Duke University Medical Center: modeling of molecular diffusion
in soft tissues.
Fred Hutchinson Cancer Research Center: modeling control of HIV
infection through structured treatment interruptions.
Michelin North America: optimization of tire design through
nonlinear multidimensional minimization.
SAS, Texas Instruments: under negotiation
