The main conference will focus on renormalization in dynamics, geometry, and number theory. In many areas of dynamics and geometry, the ideas of renormalization and self-similarity play a crucial role. These ideas involve rescaling dynamical or geometric phenomenon to observe behaviors at multiple scales.
In this conference we will focus on the following problems:
- Geometric models of digit algorithms
- Symbolic models of unipotent dynamics
- Renormalization in Interval exchanges and dynamical systems
- Number theory and circle and sphere packings
