J. Appl. Math. 2012, Article ID 185357, 18 p. (2012).

Summary: The notion of a homomorphism of approximation spaces is introduced. Some properties of such homomorphisms are investigated and some characterizations are given. Furthermore, the notion of an approximation subspace is introduced. Relations between approximation subspaces and homomorphisms are studied.
