Remarks on fixed point and equilibrium problems
Minimax theory and its applications, Tome 9 (2024) no. 1
We consider the fixed point problem as two cases of the equilibrium problem in the sense of Blum-Oettli. The first case explores the properties of maximal σ monotone operators, to propose necessary and sufficient conditions to guarantee the existence of fixed points. The second case transforms the fixed point problem, defined by an operator that has closed images not necessarily σ monotone, into an equilibrium problem, with a different approach than the first case. Also, we establish a methodology to extend any σ (with function σ bounded) monotone operator into a maximal σ monotone operator.
