ANASTASSIOU 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. https://link.springer.com/book/10.1007/978-3-031-05148-7 ------------------------------------------------------- From: Kris ONeill [log in to unmask] Date: May 09, 2022 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 Sciences - 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.

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. ------------------------------------------------------- From: Gabriele Steidl [log in to unmask] Date: May 09, 2022 Subject: Postdoc Position, TU Berlin Research Assistant with a follow-up commitment - Entgeltgruppe 13 TV-L Berliner Hochschulen.
