Sažetak

In this paper we obtain a unique common fixed point theorem,
for four self maps using a generalized altering distance function in four variables , which generalizes and improves the main theorem of Choudhury [2].
We also obtain a Gregus type common fixed point theorem for four maps as a corollary.
