This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the invariant subspace problem is studied for certain families of linear bounded operators on Banach spaces. We also consider families of positive operators on Banach lattices. This thesis is divided into four chapters. 0D0A In the first chapter , we give a brief history of the invariant subspace problem. Then the relation of the work in the thesis with the existing works on this subject is established. 0D0A The notion of a compact-friendly operator was introduced in 1994 by Y.A. Abramovich, C.D. Aliprantis, and 0. Burkinshaw. They proved that every non-zero locally quasinilpotent compact-friendly operator on a Dedekind complete Banach lattice has a non-trivial closed invariant ideal. In Chapter 2, we show that Dedekind completeness is not necessary and that the Banach lattice having separating orthomorphisms is sufficient. We also generalize a theorem due to R. Drnovsek in 2001 by using the concept of compact-friendliness. 0D0A In Chapter..3, we give an invariant subspace result for a semigroup of positive operators on a Banach space with a (Schauder) basis. This is a generalization of a theorem of Y.A. Abramovich, C.D. Aliprantis, and 0. Burkinshaw in 1995. This theorem states that for a positive continuous operator defined on a Banach space with a basis if it commutes with a non-zero positive locally quasinilpotent operator, then it has a non-trivial closed invariant subspace. By using the notion of weakly quasinilpotence introduced in 2004 by Z. Ercan and S. Önal, we then generalize our result to topological vector spaces with Markushevich basis. 0D0A In Chapter 4, collectively compact sets of linear bounded operators on infinite dimensional Banach spaces are studied in connection with the invariant subspace problem. We give some invariant subspace results with respect to the joint spectral radius and its local version for these sets. It is also shown, in a special case, that any collectively compact set of operators satisfies the Berger- Wang formula.

Book Synopsis An Invitation to Operator Theory by : Yuri A. Abramovich
Download or read book An Invitation to Operator Theory written by Yuri A. Abramovich and published by American Mathematical Soc.. This book was released on 2002 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive and reader-friendly exposition of the theory of linear operators on Banach spaces and Banach lattices using their topological and order structures and properties. Abramovich and Aliprantis give a unique presentation that includes many new and very recent developments in operator theory and also draws together results which are spread over the vast literature. For instance, invariant subspaces of positive operators and the Daugavet equation arepresented in monograph form for the first time. The authors keep the discussion self-contained and use exercises to achieve this goal. The book contains over 600 exercises to help students master the material developed in the text. The exercises are of varying degrees of difficulty and play an importantand useful role in the exposition. They help to free the proofs of the main results of some technical details but provide students with accurate and complete accounts of how such details ought to be worked out. The exercises also contain a considerable amount of additional material that includes many well-known results whose proofs are not readily available elsewhere. The companion volume, Problems in Operator Theory, also by Abramovich and Aliprantis, is available from the AMS as Volume 51 inthe Graduate Studies in Mathematics series, and it contains complete solutions to all exercises in An Invitation to Operator Theory. The solutions demonstrate explicitly technical details in the proofs of many results in operator theory, providing the reader with rigorous and complete accounts ofsuch details. Finally, the book offers a considerable amount of additional material and further developments. By adding extra material to many exercises, the authors have managed to keep the presentation as self-contained as possible. The best way of learning mathematics is by doing mathematics, and the book Problems in Operator Theory will help achieve this goal. Prerequisites to each book are the standard introductory graduate courses in real analysis, general topology, measure theory, andfunctional analysis. An Invitation to Operator Theory is suitable for graduate or advanced courses in operator theory, real analysis, integration theory, measure theory, function theory, and functional analysis. Problems in Operator Theory is a very useful supplementary text in the above areas. Bothbooks will be of great interest to researchers and students in mathematics, as well as in physics, economics, finance, engineering, and other related areas, and will make an indispensable reference tool.
Book Synopsis Invariant Subspace Theorems by : R. Tunç Misirlioglu
Download or read book Invariant Subspace Theorems written by R. Tunç Misirlioglu and published by LAP Lambert Academic Publishing. This book was released on 2010-08 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present monograph concerns with the invariant subspace problem within the context of families of linear bounded operators on Banach spaces as well as families of positive operators on Banach lattices. Although it is primarily based on the PhD thesis of the author, the monograph provides further results and information on recent advances about the topic. The general invariant subspace problem concerns linear and bounded operators on infinite-dimensional complex Hilbert spaces, and asks whether there exists a closed subspace, different than the trivial ones, that is mapped to itself by such an operator. The picture that emerged after oodles of different attempts for a possible solution to this problem for a single operator has been the subject matter of an extensive amount of research over more than seven decades, and it was only in the late 1990s that the reformulation of the invariant subspace problem for families of operators, rather than a single one, attracted the mathematical community s growing attention. In this book, we are interested in giving some results concerning the invariant subspace problem for special families of operators.

Book Synopsis Narrow Operators on Function Spaces and Vector Lattices by : Mikhail Popov
Download or read book Narrow Operators on Function Spaces and Vector Lattices written by Mikhail Popov and published by Walter de Gruyter. This book was released on 2012-12-06 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most classes of operators that are not isomorphic embeddings are characterized by some kind of a “smallness” condition. Narrow operators are those operators defined on function spaces that are “small” at {-1,0,1}-valued functions, e.g. compact operators are narrow. The original motivation to consider such operators came from theory of embeddings of Banach spaces, but since then they were also applied to the study of the Daugavet property and to other geometrical problems of functional analysis. The question of when a sum of two narrow operators is narrow, has led to deep developments of the theory of narrow operators, including an extension of the notion to vector lattices and investigations of connections to regular operators. Narrow operators were a subject of numerous investigations during the last 30 years. This monograph provides a comprehensive presentation putting them in context of modern theory. It gives an in depth systematic exposition of concepts related to and influenced by narrow operators, starting from basic results and building up to most recent developments. The authors include a complete bibliography and many attractive open problems.
Book Synopsis An Introduction to Local Spectral Theory by : K. B. Laursen
Download or read book An Introduction to Local Spectral Theory written by K. B. Laursen and published by Oxford University Press. This book was released on 2000 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern local spectral theory is built on the classical spectral theorem, a fundamental result in single-operator theory and Hilbert spaces. This book provides an in-depth introduction to the natural expansion of this fascinating topic of Banach space operator theory. It gives complete coverage of the field, including the fundamental recent work by Albrecht and Eschmeier which provides the full duality theory for Banach space operators. One of its highlights are the many characterizations of decomposable operators, and of other related, important classes of operators, including identifications of distinguished parts, and results on permanence properties of spectra with respect to several types of similarity. Written in a careful and detailed style, it contains numerous examples, many simplified proofs of classical results, extensive references, and open problems, suitable for continued research.
