New Results on the Parametrization of J-spectral Factors

چکیده
This paper considers a parametrization of a class of J spectral factors of a given J spectral density. The notion of J stable functions is introduced to define a partial ordering on the set of J spectral factors. Necessary and sufficient conditions for the existence of extremal J spectral factors are given and a number of explicit factorization results is derived which serve for the algorithmic aspects of computing specific J spectral factors.

Parametrization of Pedestrian Injuries and its Utilisation in Proving Traffic Accidents Course Using Injury Signatures and Contact Signatures
Background: The paper points out the present limited possibility of using the verbal description of injuries for the needs of experts from the field of road transportation as relevant criminalistics traces, as well as the options of the FORTIS system that creates a new area for a deeper interdisciplinary approach in the field of expert evidence. Further a description of how to create injury si...
متن کاملA Parametrization of the Minimal Square Spectral Factors of a Nonrational Spectral Density
Given a nonrational spectral density, minimality for square spectral factors with singularities in both the left and the right half planes is de ned. A parametrization of all minimal square spectral factors is then provided in terms of left inner divisors of a certain inner function depending only on the spectral density. Some results on matrix inner functions and minor complements on the Lindq...
متن کاملJ-spectral factorization for rational matrix functions with alternative realization
In this paper, recent results by Petersen and Ran on the J-spectral factorization problem to rational matrix functions with constant signature that are not necessarily analytic at infinity are extended. In particular, a full parametrization of all J̃-spectral factors that have the same pole pair as a given square J-spectral factor is given. In this case a special realization involving a quintet ...
