Continuous weakly cancellative triangular subnorms: I. Their web-geometric properties

The paper studies web-geometric properties of continuous weakly cancellative t-subnorms. Particularly, it studies the Reidemeister closure condition which is known from web geometry as a visual characterization of those loops that are associative. As a result, the paper delimits a subset of the domain of a continuous weakly cancellative t-subnorm in which the Reidemeister closure condition is necessarily satisfied.
