Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - In this book we are concerned with the study of a certain class of in nite matrices and two important properties of them: their Fredholmness and the stability of the approximation by their nite truncations. Let us take these two properties as a starting point for the big picture that shall be presented in what follows. Stability Fredholmness We think of our in nite matrices as bounded linear operators on a Banach space E of two-sided in nite sequences. Probably the simplest case to start with 2 + is the space E = of all complex-valued sequences u=(u ) for which m m= 2 |u | is summable over m Z. m Theclassofoperatorsweareinterestedinconsistsofthoseboundedandlinear operatorsonE whichcanbeapproximatedintheoperatornormbybandmatrices. We refer to them as band-dominated operators. Of course, these considerations 2 are not limited to the space E = . We will widen the selection of the underlying space E in three directions: p - We pass to the classical sequence spaces with 1 p . n - Our elements u=(u ) E have indices m Z rather than just m Z. m - We allow values u in an arbitrary xed Banach spaceX rather than C.…
