Subject: Seeking arXiv Editor

The Computing Research Repository (CoRR), also known as the Computer
Science section of, is an open source repository for
preprints in the field of computing. Authors select topic
categorizations when submitting articles, and each such category has a
volunteer editor who checks whether the category is appropriate and if
the submission is indeed a research article. Editors do not generally
review articles for quality, only for appropriateness; such reviews
typically can be done in a minute or so each. I am currently the
gatekeeper for three categories within CoRR: (1) Numerical Analysis,
(2) Mathematical Software, and (3) Computational Science, Engineering
and Finance. CoRR is looking for a volunteer willing to succeed me as
Editor. The position provides one with a unique perspective on current
research being undertaken in these areas. About 2-4 such papers are
submitted each day, so the workload is very modest. If you are
interested in performing this service to the community please contact

Subject: Announcing FEAST Eigensolver v3.0

FEAST is a free high-performance numerical library for solving the
eigenvalue problem, and obtaining all the eigenvalues and (right/left)
eigenvectors within a given search interval or arbitrary domain in the
complex plane. Its originality lies with a new transformative
numerical approach to the traditional eigenvalue algorithm design -
the FEAST algorithm. The algorithm contains elements from complex
analysis, numerical linear algebra and approximation theory. It is
defined as an optimal subspace iteration method using approximate
spectral projectors. The FEAST eigensolver combines simplicity and
efficiency and offers many important capabilities for achieving high
performance, robustness, accuracy, and scalability on parallel
architectures. The package includes flexible reverse communication
interfaces and ready to use predefined interfaces for dense, banded
and sparse systems.

The new version v3.0 of the FEAST package can address both Hermitian
and non-Hermitian eigenvalue problems (real symmetric, real
non-symmetric, complex Hermitian, complex symmetric, or complex
general systems) on both shared-memory and distributed memory
architectures (i.e contains both FEAST-SMP and FEAST-MPI
packages). The new upgrade includes, in particular:

1 Supports for non-Hermitian systems (more than 100 new routines)
2 New and improved quadrature schemes (including Zolotarev
3 Stochastic estimates for eigenvalue counts
4 Expert routines using custom contour
5 Highly-scalable banded interfaces using the new spike-smp solver

The software can be downloaded from the following website:

Remark: FEAST v2.1 (Hermitian-SMP) is also integrated into INTEL-MKL
(Intel MKL Extended Eigensolver)

Subject: New Book, Finite Dimensional Linear Systems

Announcing the May 26, 2015, publication by SIAM of:

Finite Dimensional Linear Systems, by Roger W. Brockett

xvi + 244 pages / Softcover / ISBN 978-1-611973-87-7 / List Price $74.00
/ SIAM Member Price $51.80 / Order Code CL74

Originally published in 1970, Finite Dimensional Linear Systems is a
classic textbook that provides a solid foundation for learning about
dynamical systems and encourages students to develop a reliable
intuition for problem solving. The theory of linear systems has been
the bedrock of control theory for 50 years and has served as the
springboard for many significant developments, all the while remaining
impervious to change. Since linearity lies at the heart of much of the
mathematical analysis used in applications, a firm grounding in its
central ideas is essential.

This book touches upon many of the standard topics in applied
mathematics, develops the theory of linear systems in a systematic
way, making as much use as possible of vector ideas, and contains a
number of nontrivial examples and many exercises.

PhD position "Multivariate Polynomial and Rational Interpolation and
Approximation with applications in engineering"

In several theoretical as well as computational mathematical problems,
one wants to work with complicated multivariate functions. However, in
a lot of cases performing operations with these original functions is
cumbersome and requires an unacceptably high computational effort. A
solution to this problem is to replace the original complicated
function by a function that can be handled much more easily, e.g.,
polynomial or rational functions. Within this space of simpler
functions, we can look for the function that optimizes one of several
possible criteria. The computational effort to find, e.g., a minmax
approximant is large. Instead a nearly optimal approximant can be
found by just computing the function that interpolates the original
function in certain well-chosen points, called “good points”. The
“good points” themselves can be chosen in an optimal or nearly optimal
way according to a certain optimization criterion that specifies the
“goodness” of the set of points. Further details can be found at the
project webpage

In this project, we will study “good points” for multivariate
interpolation and approximation for different function spaces as well
as “good representations” for the corresponding interpolant/
approximant. The theory of these “good points” and “good
representations” will be developed as well as the corresponding
efficient and accurate algorithms to compute them and work with
them. We will also study several applications in which these tools
could play a key role.
