摘要: In this talk, we consider an abstract differential variational inequality which consists of an evolution equation with history-dependent operator and a double nonlinear inclusion with nonmonotone perturbation. The latter arises from enthalpy formulation of heat conduction problems with phase change and nonmonotone source. We firstly introduce a hybrid iterative system by using the implicit time discretization method, pseudomonotone operators theory and a feedback iterative technique. Then, the existence and a priori estimates for solutions to a series of approximating discrete problems are established. Furthermore, through a limit procedure for solutions of the hybrid iterative system, we show the existence of solutions to the original problem. Finally we point out some problems for the further research.
