Some characterizations of granularity-wise separations are obtained by means of Pawlak rough sets and some relations among granularitywise separations are established, which makes it possible to research covering approximation spaces by logical methods and mathematical methods in computer science. Results of this paper give further applications of Pawlak rough set theory in pattern recognition and artificial intelligence.}, journal = {International Journal of Mathematical and Computational Sciences}, volume = {4}, number = {7}, year = {2010}, pages = {1005 - 1009}, ee = {https://publications.waset.org/pdf/13289}, url = {https://publications.waset.org/vol/43}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 43, 2010}, }
