Lipschitz truncations for function spaces based on $\mathbb{C}$-elliptic operators
A talk in the BI.discrete series by
Linus Behn from (Bielefeld)
| Abstract: |
The goal of Lipschitz truncations is to approximate a function by a Lipschitz continuous function while leaving it unchanged outside of a small set.
This can not be achieved by standard mollification and thus a more careful construction is needed. We first repeat this construction for Sobolev spaces and then extend it to other Sobolev-like spaces.
This spaces will revolve around $\mathbb{C}$-elliptic operators, which are a certain class of elliptic differential operators. Important examples include the gradient and the symmetric gradient.
The talk is closely related to the following talk by Stefan Schiffer (Bonn) on February 8th.
