Minimax Theorems and Qualitative Properties of the Solutions of Hemivariational Inequalities

The book explores boundary value problems (BVPs) categorized into variational and hemivariational inequalities, emphasizing their distinct characteristics. The variational inequalities relate to convex energy functions, while hemivariational inequalities address nonconvex scenarios, a field that emerged in 1981. It highlights the rapid advancements in both theoretical and applied mathematics, particularly in engineering, due to the introduction of innovative mathematical methods. The text showcases significant progress in solving complex problems across various scientific disciplines.
