Abstract:
We aim at studying the near subnormality of the unilateral weighted shifts, whose moment sequences are defined by linear recursive relations of finite order. Using the basic properties of recursive sequences, we provide a natural necessary condition, that ensure the near subnormality of this important class of weighted shifs. Some related new results are established; moreover, applications and consequences are presented; notably the notion of near subnormal completion weighted shift is implanted and explored.

Abstract:
AbstractIn this note we examine the relationships between a subnormal shift, the measure its moment sequence generates, and those of a large family of weighted shifts associated with the original shift. We examine the effects on subnormality of adding a new weight or changing a weight. We also obtain formulas for evaluating point mass at the origin for the measure associated with the shift. In addition, we examine the relationship between the measure associated with a subnormal shift and those of a family of shifts substantially different from the original shift.

The purpose of this paper is to show that the weighteds-shift operators and so the weighted shift and the right shift operators have the SVEP, but the left shift operator has not. Also, ifT,S∈B(X)are quasi-similar operators then, it is shown thatThas the SVEP iffShas the SVEP. Finally, the paper shows that the right and left shift operators are not decomposable

This thesis consists of four chapters. Chapter 1 contains the preliminaries. We give the background, notation and some results needed for this work, and we describe our main results of this thesis. In Chapter 2 we will introduce a class of weighted Bergman spaces. We then will discuss some properties about the multiplication operator, Mz , on them. We also characterize the dual spaces of these weighted Bergman spaces. In Chapter 3 we will characterize the reducing subspaces of multiple weighted shifts. The reducing subspaces of the Bergman and the Dirichlet shift of multiplicity N are portra

Abstract:
This dissertation is primarily concerned with studying the invariant subspaces of left-invertible, weighted shifts, with generalizations to left-invertible operators where applicable. The two main problems that are researched can be stated together as When does a weighted shift have the one-dimensional wandering subspace property for all of its closed, invariant subspaces? This can fail either by having a subspace that is not generated by its wandering subspace, or by having a subspace with an index greater than one. For the former we show that every left-invertible, weighted shift is similar

Abstract:
Diffusion weighted imaging (DWI) and dynamic susceptibility contrast-enhanced (DSC) perfusion-weighted imaging (PWI) are commonly employed in clinical practice and in research to give pathophysiological information for patients with acute ischemic stroke. DWI is thought to roughly reflect the severely damaged infarct core, while DSC-PWI reflects the area of hypoperfusion. The volumetric difference between DWI and DSC-PWI is termed the PWI/DWI-mismatch, and has been suggested as an MRI surrogate of the ischemic penumbra. However, due to the applicat

Abstract:
Well-bounded operators of type (B) are the building blocks for trigonometrically well-bounded, polar and AC operators. We examine the relationship between polar and AC operators of type (B) and explore the concepts of bounded variation and absolute continuity for functions defined on annuli. In 1973, Hunt, Muckenhoupt and Wheeden showed that the Hilbert transform is a bounded operator on a weighted <I>L<SUP>p</SUP></I> space precisely when the weight satisfies the <I>A<SUB>p</SUB></I> condition. This result is proved independently for <I>L<SUP>p</SUP></I> spaces over the reals, the circle and

The research problem is the increasing numbers of overweight and obese nurses working the night shift. Study on overweight and obesity among female Filipino nurses has not been conducted. It was important to conduct a research study among female Filipino nurses to find out if there are statistically significant associations between night shift work and weight gain. The purpose of this correlational and cross-sectional study was to determine if there are statistically significant associations between insufficient sleep, abnormal eating patterns, working 12-hour shifts, years of working night sh

Abstract:
Historically, regional power shifts have tended to be messy affairs. Such changes often produced not only wars, but long, drawn-out forms of conflict that devastated the regions in which they occurred. With the exception of the Cold War between the United States and the Soviet Union, none of these power-shift conflicts have yet been truly global, and it is unlikely that the rivalry between the United States and China will spill over into a global confrontation any time soon.
