Compact and Fredholm Operators

1993
The operators in infinite dimensional spaces closest to operators in finite dimensional spaces are the compact operators, which will now be studied systematically. A large number of examples of compact operators are given in the exercises.

Holomorphic Fredholm Operator Functions

1993
The purpose of this chapter is to set down some facts from operator theory, functional analysis and complex analysis that will be frequently used in the main body of the book. We do not intend to present here the whole theory of Fredholm operator functions, because it would take a book itself.
