Power Series with Bounded Coefficients. Some notes on an expansion theorem of Paley and Wiener. The use of fusion-formed compounds of polyvalent cations with aluminate, alumino-borate and -ferrite anions has been found to provide improved clarification methods for settling aqueous suspensions of solids. The use of these materials has been found to be more effective than the use of the corresponding conventional mono-valent cation compounds.

A particularly effective form of these clarifying agents is obtained when the preparation thereof is carried out by high temperature methods, which bri A General Moment Problem. Boas 1 Estimated H-index: 1. Gap and density theorems. Published on Dec 31, Norman Levinson 1 Estimated H-index: 1.

Estimated H-index: Abstract We present a novel family of continuous, linear time-frequency transforms adaptable to a multitude of nonlinear frequency scales. Similar to classical time-frequency or time-scale representations, the representation coefficients are obtained as inner products with the elements of a continuously indexed family of time-frequency atoms.

These atoms are obtained from a single prototype function, by means of modulation, translation and warping. By warping we refer to the process of nonline Frames induced by the action of continuous powers of an operator.

Casazza and Christensen introduced the notion of the reconstruction property in separable Banach spaces, which is related to some deep concepts in Banach space theory.

We discuss some types of operators associated with the reconstruction property and its related Banach frames in Banach spaces. Yan Zhang. It is known from the existing literatures that nonhomogeneous wavelet systems play a fundamental role in wavelet analysis which benefit to understanding many aspects of wavelet theory and relate to different aspects of wavelet analysis.

Reihaneh Raisi Tousi 4 Estimated H-index: 4. We give a necessary and sufficient condition for the family of representation coefficients to be a continuous shearlet frame. Furthermore relations between continuous shearlet frames associated to a given representation and its irreducible sub-representations are investi Full spark frames and totally positive matrices. In this paper we establish a connection between full spark frames and totally nonsingular matrices. Then we provide a method for constructing infinite totally positive matrices which make up a subclass of the class of totally nonsingular matrices.

Using this method we then construct a family of infinite totally positive matrices parameterized by non-negative numbers which contains, as the simplest case, the infinite Pascal matrix.

The paper ends with some examples and comments on full spark fram Global Symmetric Approximation of Frames. Published in Journal of Fourier Analysis and Applications 1. Eduardo Chiumiento 2 Estimated H-index: 2. We solve the problem of best approximation by Parseval frames to an arbitrary frame in a subspace of an infinite dimensional Hilbert space.

We explicitly describe all the solutions and we give a criterion for uniqueness. Our proof relies on the geometric structure of the set of all Parseval frames quadratically close to a given frame.
