Common Fixed Point Theorems

Brian Fisher, H. K. Pathak, Rakesh Tiwari

Abstract


In this note we establish a common fixed point theorem for a quadruple of self-mappings satisfying a generalized contractive condition in a normed space which extends the result of Rashwan [2]. We also prove some fixed point theorems with asymptotic regularity condition for a quadruple of mappings. These theorems generalize and extend results of Sastry et al. [3] and Zeqing Liu et al. [4].
