Fredholm Theory in Banach Spaces (Cambridge Tracts in Foto. Gå till. Rock climber Mikael Fredholm's biggest challenge | Romania .

In der Funktionalanalysis, einem Teilgebiet der Mathematik, ist die Klasse der Fredholm-Operatoren (nach E. I. Fredholm) eine bestimmte Klasse linearer Operatoren, die man „fast“ invertieren kann. Jedem Fredholm-Operator ordnet man eine ganze Zahl zu, diese wird Fredholm-Index, analytischer Index oder kurz Index genannt.

H. Fredholm operators are named after a Swedish mathematician, Ivar Fredholm(1866-1927), who studied integral equations. We will introduce two de nitions of a Fredholm operator and prove their equivalance. We will also discuss brie y the index map de ned on the set of Fredholm operators.

Fredholm operators and the essential spectrum by Schechter, Martin. Publication date 1965 Publisher New York: Courant Institute of Mathematical Sciences, New York

analysis and operator theory concerned with Fredholm operators, indices, resolvents, spectra, and Hilbert modules over C∗-algebras. All Banach spaces are  restriction of L to S is not a Fredholm operator. Since the theory of Fredholm operators is a useful tool in the solvability of linear boundary value problems.

Example 1.3.3. If K 2 B(X) is a compact operator then T = I ¡K is Fredholm of index 0. This follows from the Fredholm theory for compact operators. Example 1.3.4. If U is the unilateral shift operator on ‘2, then indexU = ¡1 and indexU⁄ = ¡1: With U and U⁄, we can build a Fredholm operator whose index is equal to an arbitrary

The natural inclusion X!X shows that T is a restriction of (T ) , so T is necessarily injective. === [1.10] dimker(T ) = dimcoker(T ) for 6= 0 , Tcompact This is the Fredholm alternative for operators T with Tcompact and 6= 0: either T is bijective, or 1. A bounded operator Kis call compact if and only if it is the norm limit of nite rank operators. More generally we have the following. De nition 2 (Compact operators, Reed and Simon [27, p. 199]) Let X and Y be two Banach spaces. An operator K2L(X;Y) is called compact (or completely continuous) Abstract The approximation of a holomorphic eigenvalue problem is considered.

out that many of the operators arising naturally in geometry, the Laplacian, the Dirac operator etc give rise to Fredholm operators. The following is mainly from H¨ormander Definition 16.13. Let X and Y be Banach spaces and let T : X → Y be a bounded linear operator. T is said to be Fredholm if the following hold. 1.
