Abstract :In this paper the authors introduce and characterize r-open, r-semiopen sets insert ignore into journalissuearticles values(resp. r-closed, r-semiclosed sets); and open, semiopen and semicontinuous maps insert ignore into journalissuearticles values(resp. closed, semiclosed maps); in L-fuzzy closure spaces.
