Abstract:

This paper deals with the initial-value problem of nonlinear evolution inclu-sions of the form dB(u)/dt + A(u) ∋ f, v0 B(u)(0), where the operator B is induced by a subgradient and A is pseudomonotone. Existence theorem is established via the time discretization technique and the regularization method. In contrast to the previous results, here we impose a weaker coerciveness condition on A and remove the strong monotonicity from B.

Key words: time-discretization, pseudomonotone operator, regularization
