Invariance of Hurwitz-Stability of Polynomials of Degree Five under Positive Hadamard Powers
Rola Alseidi, Raoufah Alsaidi, Jürgen Garloff
A complete characterization of the stability-preserving exponent set for fractional Hadamard powers of a monic Hurwitz-stable polynomial f of degree five is presented. The stabilit…

On the spectral properties of nonsingular matrices that are strictly sign-regular for some order with applications to totally positive discrete-time systems
Rola Alseidi, Michael Margaliot, Jürgen Garloff
A matrix is called strictly sign-regular of order (denoted by ) if all its minors are non-zero and have the same sign. For example, totally positive matrices…
