Download or read book Infinite Matrices and their Finite Sections written by Marko Lindner and published by Springer Science & Business Media. This book was released on 2006-11-10 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with the study of infinite matrices and their approximation by matrices of finite size. The main concepts presented are invertibility at infinity (closely related to Fredholmness), limit operators, and the stability and convergence of finite matrix approximations. Concrete examples are used to illustrate the results throughout, including discrete Schrödinger operators and integral and boundary integral operators arising in mathematical physics and engineering.
