The paper deals with spectral divisors of a matrix polynomial relative to a given contour. Necessary and sufficient conditions are given for the existence of spectral divisors whose behaviour at ...

Scientists successfully addressed mathematical challenges in conventional Spectral Matrix analysis, used to analyze three-component seismic signals, by introducing time-delay components. The new ...
