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 generalizations, mixed systems of common fixed point problems, systems of common fixed point problems, and common fixed point problems without convex assumptions are obtained.
Variational inequality problems are equivalent to fixed point problems.
The variational inequalities are equivalent to the fixed point problems.
(I) Application to fixed point problems for strict pseudocontractive mappings.
There are many results on loose saddle point problems, vector saddle point, and saddle point problems (see, e.g., [9 17]).
It includes several problems, namely, variational inequality problems, optimization problems, saddle point problems, fixed point problems, etc., as special cases.
The EP(1.1) includes variational inequality problems, optimization problems, Nash equilibrium problems, saddle point problems, fixed point problems, and complementary problems as special cases.
Equilibrium problems include fixed point problems, variational inequality problems, variational inclusion problems, saddle point problems, the Nash equilibrium problem, complementarity problems and so on.
We study the loose saddle point problems and vector saddle point problems for functions defined on the product of metric spaces.
