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
