A New Qualification Condition for the Maximality of the Sum of Maximal Monotone Operators in General Banach Spaces
M. Marques Alves, Benar Fux Svaiter · Journal of convex analysis · 2012
We study maximal monotonicity of the sum of maximal monotone operators in general Banach spaces. Under certain qualification condition (QC) on the domain of Fitzpatrick convex representations of the operators the sum is maximal monotone, even in nonreflexive Banach spaces.
