Some generalizations of common fixed point problems with applications
Zhe Yang · Fixed Point Theory and Applications · 2014
In this paper, we establish a unified approach to study the existence of fixed points for common fixed point problems. Moreover, we introduce mixed systems of common fixed point problems, systems of common fixed point problems and common fixed point problems without convex assumptions. As applications, we establish a general type of some set-valued variational inequalities, and we obtain some existence theorems of solutions of set-valued variational inequalities. The results of this paper improve and generalize several known results on common fixed point problems. MSC:47H10, 49J53, 49J40, 49J45.
