Let $\tau$ be the ordinal sum of preorders $\tau_1$ and $\tau_2$, and let $\mathcal R_\tau^\vee$ denote the polar dual of the translated reflexive preorder polytope. Ordinal-sum fa…

Ordinal sum structure conjecture. A similar ordinal sum structure should arise in these variants.

Uninorm decomposition conjecture. In this case, the set of all points of non-continuity is characterized by a symmetric continuous non-decreasing pseudo-function, and $U$ can be de…
