Fixed Point Theorems of Hegedus Contraction Mapping in Some Types of Distance Spaces
ABSTRACT
In the present paper, we prove some fixed point theorems of Hegedus contraction in some types of distance spaces, dislocated metric space, left dislocated metric space, right dislocated metric space and dislocated quasi-metric metric space which are generalized metrics spaces where self-distances are not necessarily zero.
