Next, we will apply the first theorem to establish the existence and uniqueness of common solution of a system of variational inequalities.enThéorèmes du point fixe commun de plusieurs fonctions avec Application aux inéquations variationnellesThéorèmes du point fixe commun de plusieurs fonctions avec Application aux inéquations variationnellesThesis
