Fuzzy Intersections and their Pictorial Representations

Triangular norms have been around since the early 1940s and have been used in the context of statistical metric space. A number of examples of existing t‐norms are given which are known to provide good models of fuzzy set‐theoretic intersections. Pictorial representations of t‐norms that have been made with the aid of a computer are presented and the relationship between t‐norms and parametrised t‐norms is discussed in this context. Several new examples of t‐norms are proposed using triangular functions.
