In this paper, we obtain a characterization theorem and some mapping theorems on paracompact locally cosmic spaces, and establish the characterizations of images of paracompact locally cosmic spaces under some sequence covering and L mapping. In addition, it is shown that paracompact locally cosmic spaces are preserved under closed L mappings and quotient ss mappings, respectively.
