Description

The goal of this series of lecture is to present the relation between the dynamics of germs $f:({\mathbb{C}}^2,0)\to ({\mathbb{C}}^2,0)$ tangent to the identity, the real-time dynamics of homogeneous vector fields in ${\mathbb{C}}^2$ and the dynamics of the geodesic flow on affine surfaces.

In the last lecture, we will try to formulate open problems concerning the dynamics of germs $f:({\mathbb{C}}^2,0)\to ({\mathbb{C}}^2,0)$ tangent to the identity, the real-time dynamics of homogeneous vector fields in ${\mathbb{C}}^2$ and the dynamics of the geodesic flow on affine surfaces.
