Workshop


Regularity Theory for Free Boundary and Geometric Variational Problems VI


Cervia, Hotel Club Dante, 15-19 June 2026


Support


This workshop is financed by the project
ERC VaReg (European Union - Horizon 2020).


Description


        This workshop is dedicated to the recent advances in the theories of

Free Boundary Problems and Minimal Surfaces

which include problems and combine tools from different fields as for instance PDEs, Calculus of Variations and Geometric Analysis.

The main topic is the regularity and the fine structure of geometric objects (free boundaries, minimal surfaces, free interfaces) obtained trough the minimization of variational functionals. The description of the local structure of these minima is a common objective for both the fields of Free Boundary Problems and Minimal Surfaces and the techniques developed in this context have found application to problems from different areas.

The workshop brings together young researchers and leading experts in these fields, the focus being on the recent important breakthroughs in the regularity of the free boundaries and minimal surfaces, in particular, on the formation and the structure of singularities.
