Lattice embeddings between types of fuzzy sets. Closed-valued fuzzy sets

F. J. Lobillo, Luis Merino, Gabriel Navarro +1

In this paper we deal with the problem of extending Zadeh's operators on fuzzy sets (FSs) to interval-valued (IVFSs), set-valued (SVFSs) and type-2 (T2FSs) fuzzy sets. Namely, it i…
