Subject: New Book, Mathematical Foundations of Finite Elements and Iterative Solvers

Mathematical Foundations of Finite Elements and Iterative Solvers
by Paolo Gatto

This textbook describes the mathematical principles of the finite
element method, a technique that turns a (linear) partial differential
equation into a discrete linear system, often amenable to fast linear
algebra. Reflecting the author's decade of experience in the field,
Mathematical Foundations of Finite Elements and Iterative Solvers:

- examines the crucial interplay between analysis, discretization, and
computations in modern numerical analysis,
- recounts historical developments leading to current state-of-the-art
techniques, and
- while self-contained, provides a clear and in-depth discussion of
several topics, including elliptic problems, continuous Galerkin
methods, iterative solvers, advection-diffusion problems, and saddle
point problems.

Accessible to readers with a beginning background in functional
analysis and linear algebra, this text can be used in graduate-level
courses on advanced numerical analysis, data science, numerical
optimization, and approximation theory.

Subject: Postdoc Position, FEM & Topology Optimization, Univ of Campinas

A call for applications for a postdoctoral position is open at the
Institute of Mathematics, Statistics and Scientific Computing of the
University of Campinas, on the topics of the project "Application of
Mixed-Hybrid Finite Element Methods to Topology Optimization including
Additive Manufacturing".

This project involves the study, development, and application of
finite element methods to problems related to topological optimization
of mechanical structures, including the additive manufacturing
process. In such problems, it is common to the multiphysics modeling,
where thermal and mechanical responses are considered, normally
written in terms of elliptic and parabolic partial differential
equations. The objective of this research is the development and use
of mixed and mixed-hybrid finite element formulations for the accurate
approximation of state variables, such as displacement and stress in
the elasticity problem and temperature and heat flow in the thermal
problem, to be used in the topological optimization.

It is recommended that the candidate has expertise in finite elements,
mathematical modeling, optimization, and scientific computing,
particularly using FEniCS.

The candidate will be based in Campinas, Brazil. The position is
initially for one year and can be renewed depending on
performance. The starting date (flexible) is from September 2022.

To apply, please send a CV and at least one reference letter to, in an email with the subject "PostDoc
Application". Applications are open until July 29, 2022.

degree in applied mathematics. More details:

Once recruited, you will perform research in a highly relevant
research area in applied mathematics that is centered around the
"turnaround in energy policy", in particular in the context of gas
networks. The main aim of the CRC/Transregio is to provide certified
novel answers to mathematical challenges arising in this context,
based on mathematical modeling, simulation, and optimization. In order
to achieve these goals new paradigms in the integration of these
disciplines and, in particular, in the interplay between integer and
nonlinear programming in the context of stochastic data have to be
established and brought to bear.

The CRC/Transregio 154 is financed by the Deutsche
Forschungsgemeinschaft (DFG) and the third funding phase is July 1,
2022, until June 30, 2026.

The call for applications is open until further notice. There is no
