Abstract
Let u and v be two n-dimensional vectors in the complex field such that v(T)u not equal 0, and let A = I - uv(T). We find all the solutions of the quadratic matrix equation AXA = XAX in various situations, with the help of a spectral perturbation result for rank-one updated matrices. Two numerical examples are given to demonstrate the effectiveness of the method, including an application of the result to a 4 x 4 equation related to the classic Yang-Baxter equation.
