Course on Singular Analysis
(online, Winter Semester 2020/21, Prof. Dr. Daniel Grieser)
Lecture Notes
There will be more as we go along ...
Literature
These two books by R. Melrose contain many details of what we are doing:
Differential Analysis on Manifolds with Corners (very systematic)
The Atiyah-Patodi-Singer Index Theorem (has many details on b-calculus)
Notes of mine of a more introductory nature:
Basics of the b-calculus
Notes on polyhomogeneous functions (somewhat preliminary, will be included in lecture notes)
Lecture Notes on Pseudodifferential Operators (in German)
Exercises
First sheet
Second sheet: Blow-ups and resolutions
Third sheet: Mellin transform, regularized integrals and push-forward theorem
