Introductory Fredholm theory and computation

We provide an introduction to Fredholm theory and discuss using the Fredholm determinant to compute pure-point spectra.

A General Fredholm Theory and Applications

The theory described here results from an attempt to find a general 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. Let us describe the general landscape in a somewhat oversimplified form. The common feature (with the exception o...
