UNIQUE FIXED POINT THEOREMS FOR CONTRACTIVE MAPS TYPE IN T 0 -QUASI-METRIC SPACES

In [2], Agyingi proved that every generalized contractive mapping defined in a q-spherically complete
T 0 -ultra-quasi-metric space has a unique fixed point. In this article, we give and prove a fixed point theorem for
C-contractive and S-contractive mappings in a bicomplete di-metric space. The connection between q-spherically
complete T 0 -ultra-quasi-metric spaces and bicomplete di-metric spaces is pointed out in Proposition 3.1.
