On lattice-ordered $t_{r}$-norms for type-2 fuzzy sets

General Mathematics 2020-04-09 v1

Abstract

In this paper, it is proved that, for the truth value algebra of interval-valued fuzzy sets, the distributive laws do not imply the monotonicity condition for the set inclusion operation. Then, a lattice-ordered trt_{r}-norm, which is not the convolution of tt-norms on [0,1][0, 1], is obtained. These results negatively answer two open problems posed by Walker and Walker in [15].
