In this paper, we define r-L-fuzzy closed convex sets and r-L-fuzzy closed neighbourhoods in an (L, M)-fuzzy topology (L, M)-fuzzy convexity spaces. Also, r-L-fuzzy neighbourhood separation properties rL-FNS_i were studied where . In addition, we also study the invariance or otherwise of these separation properties under subspace and product. @FMI
