JUN 01-06, 2008In 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.engbook parthttp://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=4630587http://ieeexplore.ieee.orgrestricted access519.8ConnectivesInferenceConormsSystemsNormsInvestigación operativa (Matemáticas)1207 Investigación Operativa
