讲座题目：Numerical Analysis of Variational and Hemivariational Inequalities with Applications
讲座摘要:
Inequality problems in mechanics can be divided into two main categories: that of variational inequalities concerned with convex energy functionals (potentials), and that of hemivariational inequalities concerned with nonsmooth and nonconvex energy functionals (superpotentials). Through the formulation of hemivariational inequalities, problems involving nonmonotone, nonsmooth and multivalued constitutive laws, forces, and boundary conditions can be treated successfully. Hemivariational inequalities have been shown to be very useful across a wide variety of subjects, ranging from nonsmooth mechanics, physics, engineering, to economics. This series of lectures will cover the following topics:
(1) basic notions and results on functional analysis, function spaces, and weak formulations of boundary value problems; (2) a brief introduction of variational and hemivariational inequalities arising in contact mechanics; (3) a review of well-posedness results of sample variational and hemivariational inequalities; (4) numerical analysis of variational and hemivariational inequalities: description of numerical methods, convergence analysis, error estimation; (5) discussion of future research topics.
