A new approach to fixed point theorems on G -metric spaces

Fixed point theorems for g-monotone maps on partially ordered S-metric spaces

“…Further, they proved that the fixed point theorems proved in G-metric spaces can be obtained by usual metric arguments. The similar approach may be found in [3]. The key of that approach is the following lemma.…”

The metric approach to fixed point theorems in metric-like spaces

“…By introducing two metrics induced from a metric-like space we show that some fixed point theorems in metric-like spaces may be deduced immediately from fixed point theorems in metric spaces. In particular, we show that This work may be seen as a continuation of [3,8] and some others in obtaining fixed point theorems on generalized metric spaces from fixed point theorems on certain metric spaces.…”

Remarks on quasi-metric spaces
