| Abstract: | By applying an existence theorem of maximizable H-quasiconcave functions on H-spaces ob-tained by the anthor,some generalizations of Fan type nonseparation theorem and existence theoremsof coincidences and zeros for set-valued maps with noncompact domains are obtained.These theo-rems improve and extend many well-known results. |

| Keywords: | H-space nonseparation coincidence and zero |
