We establish variational principles for monotone and maximal
bifunctions of Brøndsted-Rockafellar type by using our characterization of
bifunction’s maximality in reflexive Banach spaces. As applications, we give
an existence result of saddle point for convex-concave function and solve an
approximate inclusion governed by a maximal monotone operator.
