Orthogonal Systems and Convolution Operators

Written in English

Subjects:
• Mathematics

The main concern of this book is the distribution of zeros of polynomials that are orthogonal on the unit circle with respect to an indefinite weighted scalar or inner product. The first theorem of this type, proved by M. G. Krein, was a far-reaching generalization of G. Szegö"s result for the positive definite case. A continuous analogue of that theorem was proved by Krein and H. Langer. These results, as well as many generalizations and extensions, are thoroughly treated in this book. A unifying theme is the general problem of orthogonalization with invertible squares in modules over C*-algebras. Particular modules that are considered in detail include modules of matrices, matrix polynomials, matrix-valued functions, linear operators, and others. One of the central features of this book is the interplay between orthogonal polynomials and their generalizations on the one hand, and operator theory, especially the theory of Toeplitz marices and operators, and Fredholm and Wiener-Hopf operators, on the other hand. The book is of interest to both engineers and specialists in analysis.

H is the convolution operator by a blurring kernel (i.e, PSF) whose consequence is that Y lacks the high-frequency content of X. Furthermore, since the noise is Poisson, ε has a variance profile HX. The problem at, hand, then, is a deconvolution problem in the presence of Poisson noise.

An orthogonal system of vectors is a set of non-zero vectors of a Euclidean (Hilbert) space with a scalar product such that under these conditions the norm of each vector is equal to one, then is said to be an orthonormal system.A complete orthogonal (orthonormal) system of vectors is called an orthogonal (orthonormal) basis.

These scaling functions h i are used to calculate differential operators in the new coordinates, e.g., the gradient, the Laplacian, the divergence and the curl. A simple method for generating orthogonal coordinates systems in two dimensions is by a conformal mapping of a standard two-dimensional grid of Cartesian coordinates (x, y).

We will soon begin to look at a special type of series called a Fourier series but we will first need to get some concepts out of the way first. We will begin by defining two types of "systems" of functions called orthogonal systems and orthonormal systems.
