We introduce some generalizations of the contractions for multi-valued mappings and establish some fixed point theorems
for multi-valued mappings in b-metric spaces. Our results generalize and extend several known results in b-metric and metric
spaces. Some examples are included which illustrate the cases when the new results can be applied while the old ones cannot.
- Fixed points
- b-metric space
- set-valued mapping.
