We consider a higher order (in time) evolution inequality posed in the half ball, under
Dirichlet type boundary conditions. The involved elliptic operator is the sum of a Laplace …

We consider a class of nonlinear higher-order evolution inequalities posed in. Optimal
criteria for the nonexistence of weak solutions are established. Our study yields naturally …

weak solutions. Our study yields naturally optimal nonexistence results for the …
