We introduce L-spaces and the class of KKM-type mappings on L-spaces and establish some fixed point theorems for this class including Schauder′s type fixed point theorem and Fan-Browder′s type fixed point theorem in L-spaces. We also obtain a generalized Ky Fan′s matching theorem and a coincidence point theorem in L-spaces.
