The method of successive approximation enables one to construct solutions of (1), generally speaking, only for small values of λ . A method that makes it possible to solve (1) for any value of λ was first proposed by E.I. Fredholm (1903). The Fredholm index map ind : F(H) !Z is continuous, and hence locally constant by the discrete topology on Z. Explicitly, given any Fredholm operator T, there is an open neighborhood Uof Fredholm operators containing Tsuch that ind(S) = ind(T) for all S2U. One implication of this theorem is that the index is constant on connected components of F(H).

Since T K is a compact operator, indeed a Hilbert–Schmidt operator, all non-zero elements in its spectrum are eigenvalues of finite multiplicity by the general theory of Fredholm operators.

He then considers formulae that have structure similar to those obtained by Fredholm, using, and developing further, the relationship with Riesz theory. In particular, he obtains bases for the finite-dimensional subspaces figuring in the Riesz theory. Finally he returns to the study of specific constructions for various classes of operators.

Soon after Volterra began to promote this productive idea, Fredholm proved that one of the most important facts about a system of linear algebraic equations is still true for linear integral equations of a certain type: If the solution is unique whenever there is a solution, then in fact Since its inception, Fredholm theory has become an important aspect of spectral theory.

Fredholm Theory in Hilbert Space — A Concise Introductory Exposition Carlos S. Kubrusly Abstract This is a brief introduction to Fredholm theory for Hilbert space operators organized into ten sections. The classical partition of the spectrum into point, residual, and continuous spectra is reviewed in Section 1. Fredholm operators Abstract. A linear integral equation is the continuous analog of a system of linear algebraic equations.

In mathematics, Fredholm theory is a theory of integral equations. In the narrowest sense, Fredholm theory concerns itself with the solution of the Fredholm integral equation. In a broader sense, the abstract structure of Fredholm's theory is given in terms of the spectral theory of Fredholm operators and Fredholm kernels on Hilbert space.

We also establish the Fredholm property and transversality for generic S 1-invariant families of Hamiltonians and almost complex structures, In mathematics, Fredholm theory is a theory of integral equations.In the narrowest sense, Fredholm theory concerns itself with the solution of the Fredholm integral equation.In a broader sense, the abstract structure of Fredholm's theory is given in terms of the spectral theory of Fredholm operators and Fredholm kernels on Hilbert space.The theory is named in honour of Erik Ivar Fredholm.

The purpose of this chapter is to provide an introduction to some classes of operators which have their origin in the classical Fredholm theory of bounded linear operators on Banach spaces. The presentation is rather expository in style, and only a few results are mentioned here with suitable reference.
