- Abstract
- Recently, in [4], [5], [6], and [8] we have discussed the distributivity equation of implications $mathcal{I}(x,mathcal{T}_1(y,z)) = mathcal{T}_2(mathcal{I}(x,y),mathcal{I}(x,z))$ over t-representable t-norms, generated from (classical) continuous Archimedean mbox{t-norms}, in interval-valued fuzzy sets theory. In [7] we discussed similar methods, but for the following distributivity functional equation $mathcal{I}(x,mathcal{S}_1(y,z)) = mathcal{S}_2(mathcal{I}(x,y),mathcal{I}(x,z))$, when $mathcal{S}_1$, $mathcal{S}_2$ are t-representable t-conorms. In this article we continue investigations presented at previous EUSFLAT-LFA 2011, i.e., we will show all solutions for the following distributivity equation $mathcal{I}(mathcal{T}(x,y),z) = mathcal{S}(mathcal{I}(x,z),mathcal{I}(y,z))$, where $mathcal{I}$ is an unknown function, $mathcal{T}$ is a t-representable t-norm on $mathcal{L}^I$ generated from nilpotent t-norms $T_1$, $T_2$ and $mathcal{S}$ is a t-representable t-conorm on $mathcal{L}^I$ generated from strict t-conorms $S_1$, $S_2$.
