Dates: March 27 - 31, 2023
Venue: HIM lecture hall, Poppelsdorfer Allee 45, Bonn
Organizers: Valeria Banica (Sorbonne), Radu Ignat (Toulouse), Luc Nguyen (Oxford)

The main focus of the workshop is the analysis of topological and geometrical singularities in PDE problems arising in complex materials. These singularities typically exhibit themselves in the form of microstructures or defects of different types (points, lines, interfaces…). The associated models often have a variational formulation and deep analysis techniques are needed to describe the geometric structure, symmetry, stability and dynamics of these singularities. This workshop will bring together specialists in Calculus of Variations and PDEs working on singular phenomena that could give new insights into the physics of complex materials.
