Title: Potential Theory and Metastable Markov chains
Abstract: We review recent progress on potential theory for nonreversible Markov chains and on the metastable behavior of these dynamics.


Please feel free to download the workshop poster and distribute it to interested parties.


On Wednesday, February 27, in the afternoon we will go to Detmold to visit the Hermann monument and a brewery (including dinner).


If you have any questions about the workshop, please contact the IRTG office.
