Abstract

In this article, a system of Yang-Baxter-type matrix equations is studied, XAX=BXBXAX=BXB, XBX=AXAXBX=AXA, which "generalizes" the matrix Yang-Baxter equation and exhibits a broken symmetry. We investigate the solutions of this system from various geometric and topological points of view. We analyze the existence of doubly stochastic solutions and intertwining solutions to the system and describe the conditions for their existence. Furthermore, we characterize the case when AA and BB are idempotent orthogonal complements. i.e., A2=A,B2=B,AB=BA=0A^2 =A, B^2= B, AB = BA =0. We also completely characterize the set of solutions for n=2n=2 using commutative algebraic techniques.
