Employing an Implicit function to prove unified common fixed point theorems for expansive type mappings in symmetric spaces

The purpose of this paper is to prove some unified general common fixed point theorems employing absorbing property for expansive mappings governed by a relatively improved implicit function in symmetric spaces which generalizes several previously known results due to Ali and Imdad [2], Djoudi [6], Imdad and Khan [15], Pathak and Tiwari [28], Popa [30] and some others. Some related results are also derived besides furnishing illustrative example.
