RT Book, Section T1 Laws for Conjunctions and Disjunctions in Interval Type 2 Fuzzy Sets A1 Bustince, Humberto A1 Montero De Juan, Francisco Javier A1 Barrenechea, Edurne A1 Pagola, Miguel AB In this paper we study in depth certain properties of interval type 2 fuzzy sets. In particular we recall a method to construct different interval type 2 fuzzy connectives starting from an operator. We further study the law of contradiction and the law of excluded middle for these sets. Furthermore we analyze the properties: idempotency, absorption, and distributiveness.
