Subject: New Book, Fractional Inequalities in Banach Algebras


In this monograph we present generalized Caputo Fractional Ostrowski
and Gruss type inequalities involving several Banach algebra valued
functions. Furthermore, we give generalized Canavati fractional
Ostrowski, Opial, Gruss and Hilbert-Pachpatte type inequalities for
multiple Banach algebra valued functions. By applying the p-Schatten
norms over the von Neumann-Schatten classes we produce the analogous
refined and interesting inequalities. We provide many
applications. This monograph's results are expected to find
applications in many areas of pure and applied mathematics, especially
in fractional inequalities and fractional differential
equations. Other interesting applications can be in applied sciences
like geophysics, physics, chemistry, economics and engineering. This
monograph is appropriate for researchers, graduate students,
practitioners and seminars of the above disciplines, also to be in all
science and engineering libraries.

Subject: New Book, How to Be Creative: A Practical Guide ...

How to Be Creative: A Practical Guide for the Mathematical Sciences
by Nicholas J. Higham and Dennis Sherwood

Building on the authors' many years of experience running creativity
workshops, How to Be Creative: A Practical Guide for the Mathematical

- gives a six-step process for generating great ideas that can be used
by individuals or groups,
- provides examples demonstrating how these concepts have been or
might be used in practice in the mathematical sciences, and
- presents seven cases of tried and tested briefs that can be used at
creativity workshops.

With mathematically oriented models, this book is for anyone in the
mathematical sciences who wants to be more creative or who wishes to
train others in creativity.

Subject: Postdoc Position, LAPLACE-ENSEEIHT, France

Applications are invited for a postdoctoral fellowship position at

Candidates : PhD in applied mathematics (or physics but with a strong
component in numerical methods). Expertise in at least one of the
basic areas of the project is required (Boundary integral methods,
tensors, optimization).

Title : Modeling and optimization of photonic crystal fibers by
integral boundary methods, acceleration by tensor techniques.

Application context : This post-doctorate is funded by the ANR Frame
project (2022-2025) whose final ambition is to develop an innovative
fiber-based refractometric sensor integrating two technologies based
on multimode fibers and photonic crystals. This work is in response to
the critical need to better understand the ch4 cycle, the 2nd
greenhouse gas (GHG) after CO2, in aquatic environments. Among the
laboratories participating in the projects, Laplace, LAAS and the
University of Glasgow are involved in the work carried out as part of
this post-doctorate.

Topic : The research work will take place as part of the development
of an existing calculation code at LAPLACE for the simulation of
photonic crystal fibers by integral boundary methods. This code
exists in 2 versions: matlab as well as python/Fortran. The project
will have 3 main parts but the importance given to each of them can be
adapted according to the skills of the recruited candidate. The first
part will concern numerical modelling and further development in
boundary integral methods [1]. The functionalities of the code have
to be completed allowing in particular to calculate certain
configurations currently impossible to process. The second part will
aim to speed up calculations significantly by integrating a tensor
compression method based on the Quantized tensor-train (QTT) format
for linear system resolutions [2]. Finally, the last part will be
devoted to the implementation of a topological optimization method [3]
of the geometry in order to promote a distribution of the field in the
periphery of the fiber and allow optimal usage of the sensor.
