Singularity Theory / Singularitätentheorie (Wintersemester 2017/18)
ContentThis lecture is concerned with the so-called hypersurface singularities, these are special critical points of a differentiable or holomorphic function in several variables. In that sense the lecture is a natural continuation of the analysis courses. The central topic will be the classification of certain such singularities. These are essentially the so-called "elementary catastrophes" of R.Thom. To reach this classification, we will use several tools from areas like algebra (lokal rings), analysis (inverse function theorem) or differential geometry (tangent spaces and transversality). All of these notions are rather elementary and will be recalled if neccessary.
This lecture will be given in either German or English, depending on the audience.
There will be a weekly exercise sheet. Working actively on solving the problems from these sheets is an essential part of the lecture.
Prerequisits for this lecture is a good account of the content of the lectures " Analysis 1,2" and " Lineare Algebra und analytische Geometrie 1 und 2".
