Dislocated quasi-metric stability of a multiplicative inverse functional equation

A Result in Dislocated Quasi Metric Space

In this paper, we prove a fixed point theorem in dislocated quasi-metric space which extends and unifies some well-known similar results in literature. Mathematics Subject Classification: 47H10, 54H25.

A Fixed Point Theorem in Dislocated Quasi-Metric Space

The notion of dislocated quasi metric space was initiated by F. M. Zeyada, G. H. Hassan and M. A. Ahmed[18] in 2006. It is a generalization due to P. Hitzler and A. K. Seda[7] in dislocated metric. Dislocated quasi metric space differs from d islocated metric space with symmetric property. After the establishment of d islocated quasi metric space, it has emerged as important area of research ac...

Superstability and Stability of the Pexiderized Multiplicative Functional Equation

We obtain the superstability of the Pexiderized multiplicative functional equation fxy gxhy and investigate the stability of this equation in the following form: 1/1 ψx, y ≤ fxy/gxhy ≤ 1 ψx, y.
