Chapter 1On Existence of Solutions of Semilinear Impulsive Functional Differential Equations with Nonlocal Conditions

Akça, Haydar; Covachev, Valéry; Al-Zahrani, Eada

Pages: 1 –11

[The existence, uniqueness and continuous dependence of a mild solution of a semilinear impulsive functional-differential evolution nonlocal Cauchy problem in general Banach spaces are studied. Methods of fixed point theorems, of a C0 semigroup of operators and the Banach contraction theorem are...

Chapter 2On Banach-Lie Algebras, Spectral Decompositions and Complex Polarizations

Beltiţă, Daniel

Pages: 13 –38

[Complex Kähler polarizations are constructed for a class of real Banach-Lie algebras that are not necessarily L*-algebras but include all the real compact L*-algebras. The approach is based on the theory of spectral decompositions of Banach space operators, and particularly on Dunford scalar...

Chapter 3Commuting Triples of Subnormal Operators and Related Moment Problems

Bĵnzar, Tudor; Păunescu, Doru

Pages: 39 –59

[Using a new characterization for subnormality of a commuting triple of operators (due to T. Trent, {xc[12]}, for single operators, extended by P. Găvruţă and N. Suciu, {xc[4]}, for commuting pairs) we shall give necessary and sufficient conditions on a triple indexed sequence of vectors from a...

Chapter 4The Equality of the Reduced and the Full C*-Algebras and the Amenability of a Topological Groupoid

Buneci, Mădălina

Pages: 61 –78

[C. Anantharaman-Delaroche and J. Renault have proved that the amenability of a topological locally compact groupoid implies the equality of the reduced and the full C*-algebras. In this paper we shall prove the converse assertion under a technical hypothesis. We shall prove that if G is a...

Chapter 5ρ-Numerical Radius in Banach Spaces

Carrot, Laurent

Pages: 79 –101

[In this paper, we extend the definition of the ρ-numerical radius to Banach spaces. In order to do so, we use one of the classical characterizations of the Cρ classes, which can be naturally extended. Then, we give a first study of this concept. Some of the properties given in the Banach case...

Chapter 6Generalized Toeplitz Operators and Cyclic Vectors

Cassier, G.; Mahzouli, H.; Zerouali, E.H.

Pages: 103 –122

[We give in this paper some asymptotic von Neumann inequalities for power bounded operators in the class \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs}...

Chapter 7Statistical Properties of Disordered Quantum Systems

Fidaleo, Francesco; Liverani, Carlangelo

Pages: 123 –141

[We discuss two different approaches to the study of the long-time behavior of some disordered quantum anharmonic chains.]
LitStream

Chapter 8On Operator Periodically Correlated Random Fields

Gaşpar, Păstorel

Pages: 143 –156

[In {xc[3]} Gladyshev gave an interesting characterization of periodically correlatedness for the second-order one continuous time parameter univariate continuous stochastic processes, in terms of the support of an associated spectral bimeasure. Recently, Makagon {xc[6]} extended this result to...

Chapter 9Weighted Composition Operators on Hardy and Bergman Spaces

Kumar, Romesh; Partington, Jonathan R.

Pages: 157 –167

[This paper contains an analysis of weighted composition operators between Hardy and Bergman spaces of general simply-connected complex domains. Concepts studied include boundedness, compactness, boundedness below, isometry and invariant subspaces.]
LitStream

Chapter 10Integral Transforms Controlled by Maximal Functions

Martin, Mircea; Szeptycki, Pawel

Pages: 169 –184

[The paper characterizes the kernel functions on ℝn with the property that the associated convolution operators are controlled by certain maximal operators.]
