Sandra Kliem
Sandra Kliem has only started working at EURANDOM this October.
She is since then investigating how to combine coalescent behaviour of blocks at same sites with migration
on the hierarchical lattice in the spirit of the renormalization program of Dawson and Greven.
Furthermore, she kept working on the survival/extinction-behaviour of solutions to the KPP-equation
with branching white noise.
Artem Sapozhnikov
With Michael Damron (Princeton) and Balint Vagvolgyi (FU-Amsterdam) he was working on problems
related to near-critical two-dimensional percolation. In two papers we study so-called invasion percolation
on two-dimensional lattices. We obtain a comprehensive description of connectivity structure of
the invasion percolation cluster. In particular, we were able to show that the law of the invasion percolation
cluster is mutually singular with respect to the law of the incipient infinite cluster. We also made
significant progress in understanding the joint law of the so-called ponds of the invasion.
Lihu Xu
1. He will mainly concentrate on the project 'renormalization transform' with Frank den Hollander and
on the project 'functional inequalities in SPDEs'.
2. He is now very interested in the population dynamics and writing a lecture note on this topic (which
is based on the lectures given by Prof. Dawson) for the benefit of him self.
