1 Bonne année 2025

Au nom du groupe MODE, je vous souhaite à toutes et tous une très bonne année 2025.

2 Thèses, postdocs et postes

2.1 Post-doc position in the ERC project EYAWKAJKOS

source : Filippo Santambrogio
lien : http://math.univ-lyon1.fr/~santambrogio/EYAWKAJKOS.html

In the framework of the ERC project “Everything You Always Wanted to Know About the JKO Scheme” (EYAWKAJKOS) a post-doc will be hired either on Sept 2025 or on Sept 2026. The project concerns gradient flows in the Wasserstein space and their time discretization, the JKO scheme.
Applications are open now (deadline tp apply: Jan 27) for a three-year position expected to start in September 2025 (with some flexibility if needed). More details are available here: http://math.univ-lyon1.fr/~santambrogio/EYAWKAJKOS.html

3.4 Spring School and Workshop on Variational Analysis and Optimization 2025, Hanoi (Vietnam)

Variational analysis is a well-recognized area of mathematics with many applications to optimization, control, equilibria, stability, machine learning, statistics, as well as to practical models of science and technology. The underlying feature of variational analysis is the broad usage of generalized differentiation, which allows us to deal with nonsmooth functions, sets with nonsmooth boundaries, and set-valued mappings. Such objects naturally and frequently appear not only in problems with nonsmooth initial data but mainly due to employing variational or extremal principles and techniques.

Nowadays, qualitative analysis of optimization problems and equilibrium problems, as well as effective algorithms to solve the problems, rely greatly on variational analysis.

These School and Workshop “Variational Analysis and Optimization 2025” aim at creating a broad international forum to present fundamental principles of variational analysis and optimization theory, to exchange new results and novel ideas in the field. There are 62 confirmed invited speakers, many among them are internationally well-known scholars, from 17 countries.

Since March 14 will be “Pi day” (pi=3.14…), a Public Lectures Session within the Workshop is organized to highlight the beauty and importance of Mathematics and Mathematical Applications. The two lectures are given for a large audience, including the participants of the Workshop and the School.

Deadline for registration: February 16, 2025

3.5 Gian Course on Variational Analysis and structure in descent systems and Optimization, Varanasi (Inde)

source : Pierre Marechal
lien : https://forms.gle/WR9ujU33M

Variational analysis provides an adequate framework to deal with nonsmooth phenomena, which unquestionably prevail control theory, optimization and operations research: even in cases where a smooth model is conceived, very basic operations, like taking maxima or value functions, directly destroy smoothness at the points of interest. Multi-valued functions come into play in both theoretical and practical aspects to remedy this situation and unilateral analysis plays an extremely important role in this development, leading to notions of tangent cones, subdifferentials and metric slopes. In this course, starting from the classical Fenchel subdifferential of convex analysis, we shall present a general subdifferential theory for the class of Lipschitz continuous functions in relation with geometrical concepts of nonsmooth analysis such as tangent and normal cones.

Dates: April 14-18, 2025
Venue: Department of Mathematics, Institute of Science, Banaras Hindu University, Varanasi 221005, India
Course Instructor: Prof. Aris Daniilidis (Technische Universität Wien, Austria)
Course Co-Ordinator: Prof. Shashi Kant Mishra (Banaras Hindu University, Varanasi, India)
Registration deadline: March 31, 2025
