Graduate Seminar

This Graduate Seminar is open for all graduate students who are interested in “Optimization and Numerical Analysis for Partial Differential Equations with Nonsmooth Structures”. It is mainly intended as a forum for the graduate students of the IGDK to present their ongoing research infront of a friendly audience. The IGDK 1754 group in Graz is connected via video conference to the talk. Questions and interaction during the presentation are explicitly allowed.
