Subject: New Book, Ordinary and Fractional Approximation by Non-Additive Integrals


Springer series: Studies in Systems, Decision and Control, 2019
Book title: Ordinary and Fractional Approximation by Non-Additive
Integrals: Choquet, Shilkret and Sugeno Integral Approximators

Ordinary and fractional approximations by non-additive integrals,
especially by integral approximators of Choquet, Silkret and Sugeno
types are a new trend in approximation theory. These integrals are
only subadditive and only the first two are positive linear, and they
produce very fast and flexible approximations based on limited
data. We present both the univariate and multivariate cases. The
involved set functions are much weaker forms of the Lebesgue measure
and they were conceived to fulfill needs of economic theories and
other applied sciences. The presented approaches are original, and
chapters are self-contained and can be read independently. We exhibit
to the maximum our approximation methods to all possible
directions. The book's results are expected to find applications in
many areas of pure and applied mathematics, especially in
approximation theory, numerical analysis and mathematical economics in
both ordinary and fractional sense. As such this monograph is suitable
for researchers, graduate students, and seminars of the above
disciplines, also to be in all science and engineering libraries.

Subject: New Book, The GLOBAL optimization algorithm


The GLOBAL optimization algorithm - Newly Updated with Java
Implementation and Parallelization by Balazs Banhelyi, Tibor Csendes,
Balazs Levai, Laszlo Pal, and Daniel Zombori

This book explores the updated version of the GLOBAL algorithm which
contains improvements for a local search algorithm and new Java
implementations. Efficiency comparisons to earlier versions and on the
increased speed achieved by the parallelization, are detailed.
Examples are provided for students as well as researchers and
practitioners in optimization, operations research, and mathematics to
compose their own scripts with ease. A GLOBAL manual is presented in
the appendix to assist new users with modules and test functions.

GLOBAL is a successful stochastic multistart global optimization
algorithm that has passed several computational tests, and is
efficient and reliable for small to medium dimensional global
optimization problems. The algorithm uses clustering to ensure
efficiency and is modular in regard to the two local search methods it
starts with, but it can also easily apply other local techniques. The
strength of this algorithm lies in its reliability and adaptive
algorithm parameters. The GLOBAL algorithm is free to download also in
the earlier Fortran, C, and MATLAB implementations.

Subject: Hierarchical Matrices, Germany, Mar 2019


We would like to announce the next winter school on hierarchical
matrices.

Date: 4th to 8th of March, 2018
Place: Kiel University, Kiel, Germany
Organizers: Wolfgang Hackbusch, Lars Grasedyck, Steffen Boerm
Website:
https://www.math.uni-kiel.de/scicom/de/veranstaltungen/wshmat2019

Hierarchical matrices offer an efficient approach to handling
non-local operators resulting, e.g., from the discretization of
integral equations or the inversion of elliptic partial differential
equations. They rely on a decomposition of the given matrix into
sub-matrices of low numerical rank that can be represented in
factorized form. This particular representation allows us to perform
operations like the matrix-vector multiplication, the matrix
multiplication, inversion, or LR factorization in almost linear
complexity.

During the winter school, we give an introduction into fundamental
concepts, algorithms, and the theoretical background, combined with
practical exercises allowing the participants to get acquainted with
the basic algorithms. The exercises rely on the open-source library
H2Lib (http://www.h2lib.org).

Participation is free of chargqe, familiarity with the C programming
language is helpful. Please address questions and registration
requests to school@hmatrix.org

Subject: IMA Dense Granular Flows, UK, Jul 2019


Monday 1 - Thursday 4 July 2019
Centre for Mathematical Sciences, University of Cambridge, UK

Flows involving solid particulates are ubiquitous in nature and
industry alike. Such flows are found in pharmaceutical production, the
chemical industry, the food and agricultural industries, energy
production and the environment. Many unsolved problems remain,
however. In order to be able to solve problems, granular flows need to
be understood so that their behaviour can be controlled and
predicted. We are able to describe rapid granular flows, where the
particles are highly agitated and there has been some success
describing static systems. The intermediate regime, where these two
phases meet and coexist, is not as well understood and yet is the most
commonly observed behaviour of granular flow. The objective of this
meeting will be to interface the two ends of the particulate flow
spectrum - those working to understand the fundamentals of granular
flows and those attempting to control particulate flows in an
industrial setting - to develop solutions to the complex problems
presented by dense granular flows. Themes will include dense granular
flow, biological systems, self- propelled particles and geological
flows, exploring new developments in theoretical analysis and
experimental techniques. All attendees will be provided with an
opportunity to present recent work and there will be substantial time
for discussion, both during the workshop and during the evening!
Postgraduate and PhD students are particularly welcomed and oral
presentations will reflect the breadth of the field.

Invited Speakers: Professor Kimberly Hill (University of Minnesota);
Dr Chris Johnson (University of Manchester); Professor Ken Kamrin
(MIT); Lydie Staron (Institut le Rond d'Alembert, Paris)

Papers will be accepted for the conference based on a 500 word
abstract for oral or poster presentation. Abstracts should be submitted
by 31 January 2019 via https://my.ima.org.uk. Please indicate whether
your title is intended for oral or poster presentation.

Date: December 20, 2018
Subject: PhD Position, Direct Solvers for Elliptic Problems, Boise State Univ


I am seeking a talented, highly motivated and independent student
interested in pursuing a PhD in Computing, with an emphasis in
Computational Science and Engineering, at Boise State University. The
potential doctoral candidate would work in Donna Calhoun's group in
the Department of Mathematics at Boise State. The proposed project
offers an interested candidate the opportunity to work directly at the
intersection of the latest developments in numerical methods
development, scientific computing, and geophysical hazards modeling.

The aim of the proposed project is to develop a parallel, direct
solver for elliptic problems on adaptively refined Cartesian
meshes. The targeted numerical model is the dispersive correction
terms to the shallow water wave equations and the application domain
is geophysical modeling for tsunamis generated from landslides, or
other mechanisms where short wave lengths are a dominant and
significant feature. The numerical approach to be taken uses a
block-structured adaptive mesh refinement (AMR) where logically
Cartesian grids are used as patches in the AMR hierarchy. On each
patch, finite volume schemes based on the wave propagation algorithms
in Clawpack (http://www.clawpack.org) are used for hyperbolic terms.
The elliptic solver will be based on the low-rank
Hierarchical-Poincare-Stekhlov (HPS) method developed by
P. G. Martinsson and A. Gillman (SIAM J. Sci. Comput., Vol. 36 (4)
2014). The parallel adaptive framework for this project is based on
the ForestClaw code (http://www.forestclaw.org), developed by D.
Calhoun. The interested candidate should have a background in applied
mathematics and scientific computing, and should demonstrate
experience and/or a strong desire to work on development of numerical
methods and software in a C/C++/Fortran programming environment.
Strong candidates from other areas (computer science, physics
geophysics and so) will also be considered. Familiarity with parallel
programming paradigms such as MPI (for distributed computing), OpenMP
(for shared memory) or CUDA (for GPU programming) is a plus. A
successful candidate who completes a PhD with this project would be
well- positioned for employment opportunities in academics, national
labs and government agencies (such as the US Geological Survey) which
make use of geophysical modeling. This position is a National Science
Foundation funded project "Parallel, adaptive Cartesian grid
algorithms for natural hazards modeling", under the Division of
Mathematical Sciences and will be funded for 3 years. Women and
under-represented groups in the STEM fields are especially encouraged
to apply.

Please contact Donna Calhoun (donnacalhoun@boisestate.edu) if you are
interested, or go directly to the BSU PhD in Computing website at
http://computing.boisestate.edu

Applicant deadline for full consideration is January 5th, 2019.
