2023 OIST Conference

Geometric PDEs and Applications 

January 16 - 18, 2023

The past years have witnessed cutting-edge applications of geometry-related partial differential equations in material sciences, image processing, control theory, optimal transport and many other fields. Motivated by these new challenges, novel techniques have been developed for solving various nonlinear PDEs and understanding their analytic and geometric properties. 

This conference aims to bring together top mathematicians who actively contribute to research on related topics including fully nonlinear equations, calculus of variations, convex analysis, shape analysis, asymptotic behavior, geometric functional inequalities and so on. It will provide an opportunity to broaden our knowledge on a large variety of subjects in analysis and geometry as well as many new applications.
