  • Abstract
    Based on lower approximation operator C1 and upper approximation operator Cmacr1, this paper investigates granularity-wise separations in covering approximation space (U, C), where C1 and Cmacr1 are Zakowskipsilas approximation operators. By these investigations, some characterizations for granularity-wise separations are obtained and some relations among granularity-wise separations are established.
