Archimedean \(t\)-norm; extension principle; triangular norms; \(T\)-sum; L-R fuzzy numbers
Summary: The sum of L-R fuzzy numbers based on a given Archimedian continuous \(t\)-norm \(T\) is studied. A series of sufficient conditions improving those of several authors and ensuring an analytical form of the output sum is completed by a sufficient and necessary condition, i.e., the best sufficient condition. Some applications are indicated.
