In this paper, we establish some fixed point theorems for single valued and multi-valued mappings on a complete metric space. Suzuki’s and some other fixed point theorems are generalized by taking a more general contractive condition for single valued mappings. It is also proved that our result characterizes the completeness of the metric space. Further, taking generalized contractive condition, a fixed point theorem is also established for multi-valued mappings.
Mots-clés : Single valued and multi-valued mappings, Suzuki type contraction, fixed points and metric completeness.
