## Parabolic systems with rough initial data

### Fri., Oct. 13, 2009, 3:00pm, MATX 1100

Studying non-smooth geometric objects is a very important

and modern research topic in differential geometry and geometric

analysis. In particular it is interesting to know to which extent

these objects can be approximated by smooth ones.

In this talk I want to indicate how this problem can be related to the

study of systems of parabolic equations with irregular initial data.

Moreover I want to discuss various situations in which existence results

for these initial value problems have been obtained.

This is a joint work with Herbert Koch (Bonn).
