Abstract. A linear integral equation is the continuous analog of a system of linear algebraic equations. 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

Two-Dimensional Time-Reversal-Invariant Topological Insulators via Fredholm Theory. E Fonseca, J Shapiro, A Sheta, A Wang, K Yamakawa. Mathematical 

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. The Fredholm theory takes place in a new kind of spaces called polyfolds. These spaces are needed since all phenomena of inter-est are coming from analytically difficult phenomena like bubbling-off, stretching the neck, breaking of trajectories and blowing-up2. In [10] the Fredholm theory with operations which is needed for applications to Floer-theory and SFT. This theory will be described in the upcoming paper [25] and the lecture notes [18].

Fredholm theory for convolution type operators, the Nehari interpolation problem with generalizations and applications, and Toeplitz-Hausdorf type theorems.

By definition, a Fredholm operator is a bounded linear operator T : X → Y between two Banach spaces with finite-dimensional kernel and finite-dimensional (algebraic) cokernel A bounded linear operator D : X → Y between Banach spaces is called a Fredholm operator if it has finite dimensional kernel, a closed image, and a finite dimensional cokernel Y /im D. The index of a Fredholm operator D is defined by index D := dim ker D − dim coker D. Here the kernel and cokernel are to be understood as real vector spaces. Pris: 439 kr. Häftad, 2004.

These are typically the operators for which results from linear algebra naturally extend to in nite dimensional spaces. A.1. Fredholm theory In this section we discuss abstract Fredholm operators and their basic prop-erties. A bounded linear operator D: X→ Y between Banach spaces is called a Fredholm operator if it has finite dimensional kernel, a closed image, and a finite dimensional cokernel Y/imD.
