Equações Diferenciais

The regularity of solutions to the elasto-plastic problem and to variational problems of fast growth

Por Arrigo Cellina (Università di Milano-Bicocca).

Abstract: We consider the problem of the higher differentiability of solutions to some variational problems, characterized by the fast growth of the Lagrangian with respect to the variable gradient. In particular,  the case of the elasto-plastic problem, where the Lagrangian is an extended-valued function, will be discussed.
