A note on supp-preincave fuzzy sets

Abstract

The relationships between semicontinuity and preincavity of fuzzy sets are investigated in this- study. We- introduce- the- concepts- of- intermediate-point- supp- preincave- fuzzy- sets- and- weakly- supp-preincave- fuzzy- sets.- We- also- give- a- characterization- for- a- weakly- supp-preincave- fuzzy-set.-In-addition,-a-characterization-of-a-supp-preincave- fuzzy- sets- in- terms- of- its- relationship- with- intermediate- point- supp-preincavity- and- weakly- supp-preincavity,- respectively,-is-obtained.
