摘要：

In the paper, we consider some fixed point results of F-contractions for triangular alpha-admissible and triangular weak a-admissible mappings in metric-like spaces. The results on F-contraction type mappings in the context of metric-like spaces are generalized, improved, unified, and enriched. We prove the main result but using only the property (F1) of the strictly increasing mapping F : ( 0, +infinity) -> (-infinity, +infinity). Our approach gives a proper generalization of several results given in current literature.
