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