All doubly stochastic solutions to when is a permutation matrix

arXiv:2609.05577

Abstract

In this paper we obtain all doubly-stochastic solutions to the Yang-Baxter-like matrix equation when is a permutation matrix. We characterize the permutation solutions, proper doubly stochastic solutions, and we accompany our results with suitable examples.
