Um teorema de sobrejetividade para Operadores Monótonos Maximais

Abstract

In this work, was developed a Surjectivity theorem for maximal monotone operators based on the properties of Fitzpatrick function, as well as the applications arising due to this Theorem. Was also discussed the de nition of the function Fitzpatrick, whose properties have been evidenced, specially, through examples. Continuing, was proved a theorem which guarantees the maximality of the subdiferencial of a lower semi-continuous proper convex function. Above all, were discussed some elements of convex analysis and mainly of the conjugacy theory in convex analysis that supported the results presented in this work.
