Rough Dual Ideal in Lattices
In 2009, Zuhua Liao and his students induced rough sets into inclines. They put forward the concepts of upper and lower approximations of a subset in an incline, and studied some properties of and . This paper , based onthose researches ,investigated rough dual ideal in lattices, and discussed the properties of and when is a dual ideal, a prime dual ideal and a convex sublattice of .
