Sinopsis:

Excerpt from Fredholm Operators and the Essential Spectrum

We first give a complete treatment of Fredholm operators. Most of the results are found in the literature [4, but we have been able to substantially simplify proofs in sev eral instances. The deepest theorem we make use of is the closed graph theorem. We are able to avoid completely the concept of the opening between two subspaces.

Paperback. Condici�n: New. Print on Demand. This book delves into the fascinating world of Fredholm operators, a fundamental concept in functional analysis. Fredholm operators, characterized by their closed domain, finite-dimensional null space, and closed range, play a crucial role in understanding the behavior of linear equations. The author meticulously explores the essential spectrum of these operators, which reveals their resilience under various types of perturbations, a concept central to the study of their stability. The book goes beyond the traditional treatment of Fredholm operators by venturing into a detailed analysis of their invariance under compact perturbations, a significant area of research in the field. Through a careful examination of the essential spectrum, the author sheds light on the profound connection between Fredholm operators and the broader realm of linear operator theory, offering valuable insights into the nature of their stability and the implications of their behavior in various mathematical applications. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N� de ref. del art�culo: 9781332906789_0
