New Operators in Covering Rough Set Theory
Two new pairs of operators are defined incovering rough set and their properties arediscussed.Using them,two inequalities well knownin the covering rough set theory can now bemodified to become equalities.With the change,noinformation will be lost in the new expressions.Finally,we prove that the two pairs of operators areequivalent.
