Description
Nonsmooth analysis, and optimization with applications on mechanics. Nonsmoothness means the lack of derivative in the classical sense. The models are connected with convex and nonconvex analysis, variational and hemivariational inequalities as well as linear and nonlinear complementarity problems. The results are used for the study of unilateral contact problems, elastoplasticity, semipermeability problems, financial models of options and derivatives etc.
