Codice QDD 36 Titolo A Dirichlet problem with free gradient discontinuity Data 2008-09-08 Autore/i Carriero, M; Leaci, A.; Tomarelli, F. Link Download full text Abstract We prove the existence of strong solution for Blake & Zisserman functional under Dirichlet boundary condition. The result is obtained by showing partial regularity of weak solutions up to the boundary through blow-up technique and a decay property for bi-harmonic functions in half disk.
