*Correspondence: [email protected] Department of Mathematics, Bu-Ali Sina University, Hamedan, Iran Abstract In this paper, we study some fixed point theorems for self-mappings satisfying certain contraction principles on a convex complete metric space. In addition, we investigate some common fixed point theorems for a Banach operator pair under certain generalized contractions on a convex c...
