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 me. ------------------------------------------------------- From: Eric Polizzi [log in to unmask] Date: June 17, 2015 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 approximant) 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: http://www.feast-solver.org Remark: FEAST v2.1 (Hermitian-SMP) is also integrated into INTEL-MKL (Intel MKL Extended Eigensolver) ------------------------------------------------------- From: Bruce Bailey [log in to unmask] Date: June 17, 2015 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.

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 http://nalag.cs.kuleuven.be/research/projects/MUPORAIA.shtml 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.
