On a coupled fixed point problem in topological vector spaces

We establish some existence results for a generalized coupled coincidence point problem (for short, (GCCP)) in topological vector spaces. The solvability of the GCCP is presented using the Fan-KKM lemma. Also we derive the results on coupled coincidence points and coupled fixed points, which were introduced by Lakshmikantham and Ćirić and Amini-Harandi.
