Exchange Program MINTernational
2016 / 2017

With the goal of increasing the internationality of the Mathematics Programs at University of Bremen and California Polytechnic State University (San Luis Obispo), funding from MINTernational was used to promote an exchange between the two universities. As part of this, Arne Mosbach and Malte Steffens traveled to California from January 21st - February 9th, 2017 and Prof. Dr. Tony Samuel held a course on dynamical systems at the University of Bremen from November 22nd - 27th and December 19th - 23rd, 2016. We wish to thank MINTernational for their help in making this possible.


4th Bremen Winter School on Dynamics, Chaos and Applications

Oberwolfach Mini-Workshop
28th September - 4th October 2014

Differentiable Ergodic Theory, Dimension Theory and Stable Foliations- (ID 1440c)

Organisers: Eugen Mihailescu (Bucharest), Bernd Stratmann (Bremen)

Participants: M. Urbanski, J. Schmeling, A. Zdunik, B. Saussol, E. Mihailescu, Y. Coudène, M. Kessebohmer, M. Gröger, V. Mayer, J. Jaerisch, B. Bárány, A. Soós, A. Zielicz

The mini-workshop brought together experts in thermodynamical formalism, hyperbolic dynamics and dimension theory from several countries. All participants gave interesting 1-hour talks, and there was also an open problem session, where directions for future work and many open problems were discussed. Among the topics presented/discussed in the workshop were ones related to dimension theory and probability measures on fractals, various types of hyperbolicity, systems with overlaps, complex dynamics and iterated function systems.


2nd Bremen Winter School on Kleinian Groups and Transcendental Dynamics

Oberwolfach Mini-Workshop
1st - 7th January 2012

Thermodynamic Formalism, Geometry and Stochastics - (ID 1201c)

Organisers: B. O. Stratmann (Univ. Bremen) - M. Urbanski (UNT, Denton, US) - A. Zdunik (Univ. Warszawa, Poland)

Participants: K. Baranski, Ch. Dupont, M. Kesseböhmer, V. Mayer, E. Mihailescu, M. Pollicott, F. Przytycki, M. Roy, J. Schmeling, D. Simmons, B. Skorulski, B. Stratmann, H. Sumi, M. Urbanski A. Zdunik, R. Zweimüller

The workshop will be on recent progress in the area of thermodynamic formalism, an area which is central in the theory of dynamical systems. The fundamental ideas, techniques and methods associated with thermodynamic formalism have their origins in the pioneering work of Ruelle, Sinai, Bowen, Dobroushin and others, who from the late sixties until the mid seventies adapted key methods from statistical physics, in particular the theory of gas lattices, to the context of continuous dynamical systems on compact metric spaces. It was also during this period that important concepts such as topological pressure, the variational principle, equilibrium states and Gibbs states made their decisive breakthrough.
