A CHARACTERIZATION ON THE COMPLEMENTS OF THE ELEMENTS OF ROUGH LATTICE
B. Praba
|
Abstract: In this paper, we consider the information system and the corresponding rough lattice where D is the Praba join and Ñ is the Praba meet. We define the maximal and a minimal element of this lattice and prove its existence, also we define the complement of the elements in T. The complement of an element for is established. These concepts are illustrated through examples. |
Keywords and phrases: information system, roughset, poset, least upper bound, greatest lower bound, lattice, Boolean algebra. |
