Individual Volterra–Lyapunov stability implies a non-square D-stability-like property
Individual Volterra–Lyapunov stability implies a non-square D-stability-like property
Let be a real nonsquare matrix. Let be the index set consisting of -tuples of integers in the range . For , let denote the corresponding matrix associated with the block diagonal non-square matrix , and let denote the real part of the -th eigenvalue of a matrix . Individual Volterra–Lyapunov stability conjecture. If is an individual Volterra–Lyapunov stable matrix, then there exists a block diagonal non-square matrix such that, for every non-negative diagonal matrix and every ,
The claim proposes a sufficient spectral property associated with individual Volterra–Lyapunov stability for nonsquare matrices; the supplied text does not establish it or provide evidence that it has been resolved.
