摘要: Abstract In this work we solve the problem of a common solution to Lyapunov equation for 2 × 2 complex matrices. We show that necessary and sufficient conditions existence matrices A B is ( + i αI )( βI ) −1 have no negative real eigenvalues all α , β ∈ R . how these results relate special class 4 × 4
