Abstract
In this paper we prove that a given set K is approximately weakly invariant with respect to the fully nonlinear differential inclusion
, where A is an m-dissipative operator, and F is a given multi-function in a Banach space, if and only if the set \({F(\xi)}\) is A-quasi-tangent to the set K, for every \({{\xi \in K}}\) . As an application, we establish that the approximate solutions of the given differential inclusion approximate the solutions of the relaxed (convexified) nonlinear differential inclusion
, with no hypotheses of Lipschitz type for multi-function F.
