Abstract

In this paper, we study the algebraic structures of fuzzy soft sets. Some operations on fuzzy soft sets are introduced and several related properties are investigated. Furthermore, two lattice structures of fuzzy soft sets are established. It is proved that certain De Morgan's laws hold in fuzzy soft set theory.
