Hilbert extended Fredholm's work to include a complete eigenvalue theory for the Fredholm integral equation. This work led directly to the theory of Hilbert spaces. A GENERAL FREDHOLM THEORY AND APPLICATIONS H. HOFER† The theory described here results from an attempt to find a gen-eral abstract framework in which various theories, like Gromov-Witten Theory (GW), Floer Theory (FT), Contact Homology (CH) and more generally Symplectic Field Theory (SFT) can be understood from a general point of view.

We shall study r-Fredholm, Fredholm theory and transversality for the parametrized and for the S1-invariant symplectic action . By Frédéric Bourgeois and Alexandru Oancea. Cite . 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 theory is named in honour of Erik Ivar Fredholm. Let D: X→ Y be a Fredholm operator (i) If K: X→ Y is a compact operator then D+ Kis a Fredholm operator and index(D+K) = indexD. (ii) There exists an ε>0 such that if P: X→ Y is a bounded linear operator with kPk <εthen D+P is a Fredholm operator and index(D+P) = indexD. Proof. The assertions about the Fredholm property follow immediately from Fredholm Theory April 25, 2018 Roughly speaking, Fredholm theory consists of the study of operators of the form I+ A where Ais compact. From this point on, we will also refer to I+ Aas Fredholm operators.

He is forced to assume that his eigenvalues are not multiple (although he relaxes this assumption toward the end of his paper). There is no significant use of operators.
