The workshop will focus on the computational and visualization aspects of renormalization, with an important component of the workshop being a Sage Days in which participants work to develop and optimize software that facilitates experiment and conjecture in geometry, dynamics, probability, and number theory.
There will be 2 hour problem sessions in the mornings focusing on the computational and experimental aspects of
• Geometry,
• Dynamics
• and Number Theory
There will also be a course taught by Samuel Lelievre and Thierry Monteil on the use of Sage, CoCalc, and Jupyter.
