Approximations in a hyperlattice by using set-valued homomorphisms
In this paper, the concepts of set-valued homomorphism and strong setvalued homomorphism of a hyperlattice are introduced. The notions
of generalized lower and upper approximation operators constructed
by means of a set-valued mapping are provided. We also propose the
notions of generalized lower and upper approximations with respect to
a hyperideal of a hyperlattice which is an extended notion of rough
hyperideal in a hyperlattice and discuss some significiant properties of
them.
