Infinite dimensional Teichmüller spaces
Teichmüeller theory is an important area of modern mathematics with links to many other
subjects. Much of the theory focusses on Riemann surfaces of finite analytic type, but in this
mini-course we will survey results in Teichmüller theory which hold for all Riemann surfaces,
and in particular in the case of infinite analytic type. We will discuss the topics including:
- Quasiconformal mappings and their basic properties;
- Teichmüller space, its complex structure, tangent space;
- Biholomorphic maps between Teichmüller spaces;
- The geometry of Teichmüller space, extremal and uniquely extremal maps, geodesics;
- The bi-Lipschitz structure of Teichmüller space.
Wind tree models
Wind-tree models are 2D Boltzmann gas models where a point-particle moves at unit speed
with perfect bounces off rectangular obstacles in the plane. Paul and Tatiana Ehrenfest
introduced them in 1912 with randomly placed obstacles; in the 1980s J. Hardy and J. Weber
introduced lattice-periodic wind-tree models: obstacles at integer points, sides horizontal
By relating these models to infinite-area translation surfaces and using the dynamics of
genus two translation surfaces, explored and explained in great detail in recent years, one
can gain insight into the following dynamical questions:
- Does a generic trajectory come back arbitrarily near its starting point? (recurrence versus
- How fast does a particle explore the billiard? (diffusion)
- Do particles explore every portion of the space? (minimality and ergodicity)
