The study of complementarity problems is now an interesting mathematical
subject with many applications in optimization, game theory, stochastic
optimal control, engineering, economics etc. This subject has deep
relations with important domains of fundamental mathematics such as
fixed point theory, ordered spaces, nonlinear analysis, topological
degree, the study of variational inequalities and also with mathematical
modeling and numerical analysis. Researchers and graduate students
interested in mathematical modeling or nonlinear analysis will find here
interesting and fascinating results.
