Subject: New Book, Set Theory and Its Applications in Physics and Computing


Why learn set theory? This book provides the answer - it is
interesting, and also useful! Taking a new approach and looking from a
fresh perspective, the discussion flows in a friendly and transparent
way, supplemented with a lot of examples and figures. This makes the
theory easily comprehensible: the proofs get vivid and visual,
enveloped with interesting applications for students in (applied)
math, physics, and engineering.

Given the theory and the applications, the book could serve as a
textbook in four (undergraduate) math courses: Introduction to set
theory and its application; Chaos theory and stability - a geometrical
point of view; Functional analysis - Han-Banach theory; and
Cryptography with quantum computing. It teaches set theory from the
basics, including the axiom of choice, the well ordering theorem, and
Zorn's lemma. Furthermore, it uses Cantor's set to introduce chaos
theory from a geometrical point of view. Moreover, it introduces the
binomial formula (and other related formulas), and uses them in
quantum statistical mechanics. And finally, it uses Zorn's lemma in
functional analysis, general relativity, and quantum mechanics. There
are also practical applications in cryptography, error correction,
quantum computing and programming.

Subject: PhD Position, Iterative solvers, EDF/Cerfacs, France


An industrially funded 3-year PhD position is available jointly
supervised by EDF R&D (French Electricity Company, Palaiseau) and
Cerfacs (Toulouse).

The project focuses on highly scalable solvers for two-phase two
component flow in porous medium for hydro-mechanical models. In
particular, we want to design an iterative solver for linear systems
arising in the modeling of gas injection in a water-saturated host
rock with the presence of engineered materials such as concrete or
backfill. The storage zone is then a highly heterogeneous porous
medium, almost entirely saturated with water, that is undergoing
several cycles of saturation- desaturation of water during up to one
hundred thousand years.

Requirements: MSc degree or equivalent with a background in one or
several of the following topics: engineering, computational mechanics,
high performance computing, numerical methods, applied
mathematics. The PhD student will be based at EDF R&D (Palaiseau,
France) with a stay at Cerfacs (Toulouse, France) for a period to be
defined.
