Subject: LA Software Survey of Freely Available Software to be Updated

We are planning to update the survey of freely available software for
the solution of linear algebra problems. The current version of the
survey can be found at:

The aim is to put in "one place" the source code that is freely
available for solving problems in numerical linear algebra,
specifically dense, sparse direct and iterative systems and sparse
iterative eigenvalue problems.  Please send Dalal Sukkari
[log in to unmask] updates and corrections. We will post a note on
the na-digest when the new list is available.

Subject: New Book, Constructive Fractional Analysis with Applications

George A. Anastassiou
Constructive Fractional Analysis with Applications, SPRINGER 2021

Constructive and Computational Fractional Analysis recently are more
and more in the center of mathematics because their great applications
in the real world. In this monograph all presented is original work by
the author given at a very general level to cover a maximum number of
cases in various applications. The author applies generalized
fractional differentiation techniques of Riemann-Liouville, Caputo and
Canavati types and of fractional variable order to various kinds of
inequalities such as of Opial, Hardy, Hilbert-Pachpatte and on the
spherical shell. He continues with E. R. Love left and right sides
fractional integral inequalities. They follow fractional Landau
inequalities, of left and right sides, univariate and multivariate,
including ones for Semigroups.These are developed to all possible
directions and right side multivariate fractional Taylor formulae are
proven for the purpose. It continues with several Gronwall fractional
inequalities of variable order. The last part of book includes
constructive approximation theory, it presents: ordinary and
fractional approximations by positive sublinear operators, and high
order approximation by multivariate generalized Picard,
Gauss-Weierstrass, Poisson-Cauchy and Trigonometric singular
integrals. This book results are expected to find applications in many
areas of pure and applied mathematics. 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.

IMA Mathematics 2021 Online Series
6 and 25 May 2021, Online Event via Zoom

For a number of years, the IMA has been running a series of
conferences to promote mathematics with the aim of demonstrating to
both mathematicians and non-mathematicians the many uses of modern
mathematics. Following last summer's very successful IMA
Mathematics 2020 series collaboration with the Newton Gateway to
Mathematics, we are pleased to announce two events for 2021 taking
place this May.  The first talk at the 6 May event will be from Nick
Higham who has been awarded the Gold Medal award in recognition of
outstanding contributions to mathematics and its applications. This
will be followed by Jane Leeks and David Abrahams discussing future
developments in mathematical sciences knowledge exchange. (See the
event page for further details) On Tuesday 25 May, we will have two
talks which feature the work of V-KEMS (Virtual Forum for Knowledge
Exchange in Mathematical Sciences). Presentations will feature the
work of two very successful virtual study groups, which ran in the
earlier this year, on Reducing the Risk of Covid-10 Transmission on
Trains and Modelling Solutions to the Impact of COVID-19 on
Cardiovascular Waiting Lists. (See the event page for further

Registration for both weeks is currently open at Registration closes on 3 May for Week One and
21 May for Week Two.

Subject: Call for Minisymposia, DMV-OMG Meeting, Germany, Sep 2021

We call for proposals for minisymposia for the DMV-OMG-conference
which is held at Passau from September 27 to October 1 2021.
We welcome applications in all areas of mathematics.

A minisymposium (MS) is generally a session of 4 or more coordinated
presentations on a single topic of substantial current interest and
importance in mathematics and its applications.  The MS organizer is
the chair of the minisymposium and may also be one of the speakers
within the minisymposium.  You can indicate one talk as a 50 minute
keynote talk, all remaining talks will be 25 minute
talks. Minisymposia may be held in English or German.

The scientific committee will decide on the minisymposia.  To apply
for a minisymposium send an email to [log in to unmask] .
Your application of not more than 2 pages shall include Your name,
affiliation, address, email, phone number, website; Your co-chair's
name, affiliation, address, email, phone number, website; Title of the
minisymposium; Scientific abstract; A short description on the
importance of the topic; At least four confirmed speakers for your
minisymposium; Decision whether you are planning a fully virtual or an
in person minisymposium.  (Note: The local organizers will not provide
a hybrid solution for minisymposia. The local organizers may decide to
host a fully virtual conference, if the situation caused by the
pandemic requires this.)
