| Abstract: | r-semi-preopen sets,r-semi-preclosed sets,r-semi-preinterior and r-semi-preclosure are defined in L-smooth topological spaces,some of their basic properties are studied.Meanwhile,the concepts of L-smooth semi-precontinuous,semi-preopen as well as semi-preclosed mappings are introduced.Some of their characteristic properties are given.Therefore,the existing results are generalized. |
