Workshop Phase Transitions and Random Trees 2017

13.-14.07.2017, Room M614, TU Dortmund, Germany

Trees in Dortmund

This workshop is part of the qualification program of the Research Training Group 2131, "High-dimensional Phenomena in Probability - Fluctuations and Discontinuity", funded by the Deutsche Forschungsgemeinschaft.

GRK 2131


Random trees but also approximately tree-like complex networks are at heart of many challenging stochastic models. Key examples are branching processes, branching random walks, interacting stochastic processes on complex networks, search trees, to name just a few. It turns out that these models often undergo phase transitions as the size of the system increases.

A key question is: How does the underlying tree(-like) structure create or affect phase transitions?

Here, phase transitions are understood in a broad sense meaning an abrupt qualitative change in the behaviour of the model. Specific manifestations of them include

  • asymptotic loss of analyticity for a global functional of the system,
  • transition from asymptotic normality to stable heavy-tailed behaviour;
  • sudden failure of convergence, etc.

It is the goal of this workshop to bring young researchers and PhD students working in the areas of branching processes, stochastic processes with interacting components, complex networks together in order to broaden the understanding of the models and methods coming from these areas, to cross-fertilize ideas and to foster scientific collaboration.

Venue & Travel

The workshop takes place in Room M614 on the 6th floor of the Math Building. This is the tallest building on campus (Campus Nord), easily identified by the rotating letters "tu" on its top.

Address: Vogelpothsweg 87, 44229 Dortmund, Germany

See here for information how to get to the campus: Directions

From within Germany, Dortmund can easily be reached by train. There is also a direct train (Thalys) to Paris. The closest international airport is Düsseldorf (DUS) (about 1h by direct train connection); from Frankfurt/Main airport (FRA) it takes about 2:30 h.


We will arrange the accomodation for the invited speakers.

You can book your hotel via the website DortmundTourism. We recommend to book a hotel in the city center, close to the main train station (from there, take S1 to Dortmund University). The invited speakers will stay in "CityHotel Dortmund".


Participation in the workshop is free of charge. For organisational purposes, a registration is required. If you would like to attend the workshop, please go to Registration and fill out the form provided there. Please note that talks are on invitation only.
