A topological proof of Terao's generalized Arrow's Impossibility Theorem

Autor: Okura, Takuma

In Terao [24], Hiroaki Terao defined and studied "admissible map", which is a generalization of "social welfare function" in the context of hyperplane arrangements. Using this, he proved a generalized Arrow's Impossibility Theorem using combinatorial

We report the first example of a mechanochromic compound that can switch between four individual types of photoluminescence in the solid state.
In this study, we report the interconvertible tetracolored solid state photoluminescence of gold(i) i
