Abstract—The purpose of this paper is to investigate FC-projective comodules and FC-projective dimensions. We introduce the concepts of copure exact sequences and FC-projective comodules, and give some equivalent characterizations of FC-projective modules. We also define FC-projective dimensions, which is similar to projective dimensions. We characterize semihereditary and coregular coalgebras related to FC-projective comodules.
Keywords—Coalgebra, comodule, FC-projective comodule, FC-projective dimension, semihereditary coalgebra, coregular coalgebra
