THE IMPLEMENTATION OF A ROUGH SET OF PROJECTIVE MODULE

In ring and module theory, one concept is the projective module. A said to be if it a direct sum of independent modules. (U, R) an approximation space with non-empty set equivalence relation If X subset U, we can form upper lower approximation. rough Apr(X) not equal under Apr(X). The theory applies algebraic structures, including groups, rings, modules, homomorphisms. this study, will investigate properties
