Abstract

The (@a,T)-migrative triangular subnorms, where T stands for the three prototype triangular norms (namely the product, the Lukasiewicz t-norm and the minimum), are investigated in detail. The paper gives necessary and sufficient conditions under which a triangular subnorm with a continuous additive generator is (@a,T)-migrative with respect to any of the three prototype triangular norms.
