Some Existence Theorems for Nonconvex Variational Inequalities Problems

open access: yesAbstract and Applied Analysis, 2010
By using nonsmooth analysis knowledge, we provide the conditions for existence solutions of the variational inequalities problems in nonconvex setting. We also show that the strongly monotonic assumption of the mapping may not need for the existence of ...
