Doagooei A R, Mohebi H. Sum Formula for Maximal Abstract Monotonicity and Abstract Rockafellar’s Surjectivity Theorem. IJMSI. 2013; 8 (2) :85-100 URL: http://ijmsi.ir/article-1-507-en.html
In this paper, we present an example in which the sum of two maximal abstract monotone operators is maximal. Also, we shall show that the necessary condition for Rockafellar’s surjectivity which was obtained in ([19], Theorem 4.3) can be sufficient.
