Abstract
(English)
This note deals with the initial value problem for the abstract nonlinear nonlocal equation $ (A u)' + (B u) ni f $, where $ A $ is a possibly degenerate maximal monotone operator from the Hilbert space $ V $ to its dual space $ V ^* $, while $ B $ is a nonlocal maximal monotone operator from $ L^2(0,T,V) $ to $ L^2(0,T;V^*) $. Assuming suitable boundedness and coerciveness conditions and letting $ A $ be a subgradient, existence of a solution is established by making use of an approximation procedure. Applications to various classes of degenerate nonlinear integrodifferential equations are discussed.
