Abstract: Let X be a real separable reflexive Banach space, $${X^*}$$ its dual space, and let T: $X \to {X^*}$ be a maximal monotone operator, P :$X \to {X^*}$ a quasi-bounded generalized pseudomonotone operator or T-pseudomonotone operator. In this paper, We have constructed a topological degree for the operator(T+P). As a by products surjectvity result is obtained. In particular, we have given a partially affirmative answer to a Browder's question by using a topological method (of., Mathematical Developments arising from Hilbert Problems, Vol. 1(1976), 68—73 AMS)
