Subject: Alan Feldstein, 1945-1922

We are sad to report that Alan Feldstein, Emeritus Professor at
Arizona State University passed away on January 29, 2022. He was a
prolific and highly cited scholar who published dozens of
peer-reviewed articles in mathematics journals, conducted national
security research for the government, recruited high-caliber
professors to the ASU Mathematics Department, organized conferences on
the numerical solution of Volterra equations, and mentored doctoral
students in the field of applied mathematics. His scientific activity
was mostly dedicated to the numerical solution of delay differential
equations and computer arithmetic, where he made many important and
highly cited contributions.

In the late 1950s, Alan worked on classified projects at the Los
Alamos National Laboratory in New Mexico, which designed nuclear
weapons, and was exposed to radioactive fallout during atomic testing
on the Pacifica toll Eniwetok in the Marshall Islands. He later worked
as a research consultant on classified projects for the Lawrence
Livermore National Laboratory in California and the Naval Research
Laboratory in Washington, DC. Alan earned a PhD in mathematics from
UCLA in 1964, then served on the faculties at UCLA, Brown University
and the University of Virginia. Alan became a professor of
mathematics at Arizona State University in 1970 and served for 31
years, until his 2001 retirement.

Subject: New Book, Iterative Methods and Preconditioners for Systems

of Linear Equations

Iterative Methods and Preconditioners for Systems of Linear Equations
by Gabriele Ciaramella and Martin J. Gander

Iterative methods use successive approximations to obtain more
accurate solutions. This book gives an introduction to iterative
methods and preconditioning for solving discretized elliptic partial
differential equations and optimal control problems governed by the
Laplace equation, for which the use of matrix-free procedures is
crucial. All methods are explained and analyzed starting from the
historical ideas of the inventors, which are often quoted from their
seminal works. Iterative Methods and Preconditioners for Systems of
Linear Equations grew out of a set of lecture notes that were improved
and enriched over time, resulting in a clear focus for the teaching
methodology, which: presents historical background, derives complete
convergence estimates for all methods, illustrates and provides MATLAB
codes for all methods, and studies and tests all preconditioners first
as stationary iterative solvers.

This textbook is appropriate for undergraduate and graduate students
in need of an overview or of deeper knowledge about iterative
methods. It can be used in courses on Advanced Numerical Analysis,
Special Topics on Numerical Analysis, Topics on Data Science, Topics
on Numerical Optimization, and Topics on Approximation
Theory. Scientists and engineers interested in new topics and
applications will also find the text useful.
