Christoph auf der Horst,Alfons Labisch in the same way as linear transformations on ℂ. are represented by finite matrices. In this way the chapter may be viewed as a beginning of a theory of infinite matrices. As may be expected, analysis plays a very important role.

Heine beim Wort genommen: Vergeltungrential equations give rise to an important class of unbounded linear operators which are not defined on all of .([., .]). In this chapter an introduction to unbounded operators is presented which includes the spectral theorem for the Sturm-Liouville operator. Simple examples of the spectral theory
