Exceptional family of elements for a generalized set-valued variational inequality in Banach spaces

This article introduces a new concept of an exceptional family of elements for a generalized set-valued variational inequality in Banach spaces. By using this concept and the degree theory for the generalized set-valued variational inequality introduced by Wang and Huang [Zh.B. Wang and N.J. Huang, Degree theory for a generalized set-valued variational inequality with an application in Banach spaces, J. Glob. Optim. 49 (2011), pp. 343-357], some solvability results for the generalized set-valued variational inequality and its special cases are given in Banach spaces under suitable conditions.
