Eigenvalues of lyapunov operator
WebMay 5, 2015 · The problem of finding eigenvalues for non-hermitian (and non-symmetric) matrices is very unstable; it is quite hard to solve numerically (close to impossible) and can't be solved in radicals for matrices of size at least $5$. WebDec 18, 2013 · We propose an approach for constructing Lyapunov function in quadratic form of a differential system. First, positive polynomial system is obtained via the local property of the Lyapunov function as well as its derivative. Then, the positive polynomial system is converted into an equation system by adding some variables. Finally, …
