  • Some new coincidence theorems involving a new class of set-valued mappings containing composites of acyclic mappings defined on a contractible space are proved.As applications,some best approximation theorems and coincidence theorems for set-valued mappings are also given.A number of known results in recent literature are improved and generalized by the thorems in this paper.
