Gregus-Type Common Fixed Point Theorems for Tangential Multivalued Mappings of Integral Type in Metric Spaces
The concept of tangential for single-valued mappings is extended to multivalued mappings and used to prove the existence of a common fixed point theorem of Gregus type for four mappings satisfying a strict general contractive condition of integral type. Consequently, several known fixed point result...

| Summary: | The concept of tangential for single-valued
mappings is extended to multivalued mappings and used to prove
the existence of a common fixed point theorem of Gregus type for
four mappings satisfying a strict general contractive condition of
integral type. Consequently, several known fixed point results generalized
and improved the corresponding recent result of Pathak and
Shahzad (2009) and many authors. |
