# Events Winter Semester 2019/2020

##### PhD Seminar and PhD Day

We are happy to introduce you to the talks of our PhD seminar and PhD day!

Next PhD Seminar: 11.02.2020, 16:30-17:00. Philipp Bartmann (Universität Potsdam)

• Title: Boundary Regularity for Elliptic Partial Differential Equations
• Abstract: The behaviour of solutions to elliptic PDE's at the boundary of a domain $\Omega$ depends heavily on the geometry of $\partial\Omega$. One is therefore interested in criteria to $\Omega$ that ensure differentiability, Hölder-continuity or even more regularity up to the boundary.
We will give a brief overview on the classical results in this regard and introduce an optimal geometric condition - so called $\gamma$-convexity - that guarantees differentiability at the boundary.

# New here?

If you recently started your Ph.D. at our Institute, please do the following:

• Add yourself to our PhD student mailing list mathe-doc. (To do this write a request to Mr. Dathe {dathe[at]uni-potsdam.de} or to one of the PhD representatives.)
• Participate in our one-per-semester PhD day and in our monthly PhD seminar! Find out what other PhD students are working on or give a talk yourself!

# Ph.D.Representatives

The current Ph.D. representatives are Florian Fischer and Undine Falkenhagen.

What do we do?

• Come to us with any questions, concerns or problems regarding your PhD studies.
• We represent the group of PhD students in mathematics in the Institutsrat.
• We organize the PhD day and PhD seminar together with the organizing committee.
• We organize regular meetings for PhD students.

If you are interested in our events, or if you want to organize one yourself, get on our mailing list "mathe-doc"and/or contact us.
