The aim of this note is to prove some fixed and common fixed point theorems in complete metric spaces for self-maps verifying generalized contractive conditions close to that one introduced by M. S. Khan, M. Swaleh and S. Sessa in [6]. Moreover our results utilize much weaker conditions on the functions altering the distances between the points. Our main result unifies and improves the main results of papers [I], [4], [6] and [8].
