On a Hardy Space Approach to the Analysis of Spectral Factors
نویسندگان
چکیده
The paper presents a study of several problems related to spectral factorizations. We assume only a very weak form of coercivity for the p× p spectral function Φ and look at the set Wm of all rectangular, p × m spectral factors. The main object is the arithmetization of the geometry of the set of minimal, stable spectral factors by employing Hardy space techniques and the arithmetic of inner functions. Particular attention is paid to the study of various partial orders associated with the set of spectral factors.

An extension theorem for finite positive measures on surfaces of finite dimensional unit balls in Hilbert spaces
A consistency criteria is given for a certain class of finite positive measures on the surfaces of the finite dimensional unit balls in a real separable Hilbert space. It is proved, through a Kolmogorov type existence theorem, that the class induces a unique positive measure on the surface of the unit ball in the Hilbert space. As an application, this will naturally accomplish the work of Kante...
متن کاملOn the Lyapunov Equation, Coinvariant Subspaces and Some Problems Related to Spectral Factorizations
A geometric approach to stochastic realization theory, and hence to spectral factorization problems, has been developed by Lindquist and Picci [1985,1991], Lindquist, Michaletzky and Picci [1995]. Most of this work was done abstractly. Fuhrmann and Gombani [1998] adopted an entirely Hardy space approach to this set of problems, studying the set of rectangular spectral factors of given size for ...
متن کاملRepresenting Spectral data using LabPQR color space in comparison to PCA method
In many applications of color technology such as spectral color reproduction it is of interest to represent the spectral data with lower dimensions than spectral space’s dimensions. It is more than half of a century that Principal Component Analysis PCA method has been applied to find the number of independent basis vectors of spectral dataset and representing spectral reflectance with lower di...
متن کاملBilateral composition operators on vector-valued Hardy spaces
Let $T$ be a bounded operator on the Banach space $X$ and $ph$ be an analytic self-map of the unit disk $Bbb{D}$. We investigate some operator theoretic properties of bilateral composition operator $C_{ph, T}: f ri T circ f circ ph$ on the vector-valued Hardy space $H^p(X)$ for $1 leq p leq +infty$. Compactness and weak compactness of $C_{ph, T}$ on $H^p(X)$ are characterized an...
متن کاملTarget Detection Improvements in Hyperspectral Images by Adjusting Band Weights and Identifying end-members in Feature Space Clusters
Spectral target detection could be regarded as one of the strategic applications of hyperspectral data analysis. The presence of targets in an area smaller than a pixel’s ground coverage has led to the development of spectral un-mixing methods to detect these types of targets. Usually, in the spectral un-mixing algorithms, the similar weights have been assumed for spectral bands. Howe...
