Mathematical Background

  • Ole ChristensenEmail author
Part of the Applied and Numerical Harmonic Analysis book series (ANHA)


This introductory chapter collects basic results from linear algebra and real analysis that will be needed throughout the book. The chapter has the status of a tool box, and the presentation is more compressed than in the rest of the book. None of the stated results are proved, but most of the definitions and key results are illustrated by examples. In many cases a guide to a proof is stated as an exercise.
