ERC Workshop on Existence and Regularity for Nonlinear Systems of Partial Differential Equations*

Critical variational problems in the space of functions of bounded variation

speaker: Michel Willem (UCL, Louvain, Belgium)

abstract: We prove, by a new elementary method, the existence of optimal functions for the Poincaré inequality in BV. Using a relative isoperimetric inequality, we prove also some estimates for the best constant of the Poincaré inequality.
