Rough Set Algebra and Lattice Implication Algebra
Keyun Qin · Journal of Southwest Jiaotong University · 2004
The relation between rough set algebra and lattice implication algebra was studied, and the method of constructing lattice implication algebra from rough set algebra was presented. Based on the atoms and congruence relations of approximation algebra, it is proved that rough set algebra becomes lattice implication algebra if proper implication and complement operators are selected.
