Aim and Scope
The aim of the summer school is to provide an introduction to positive geometry and scattering amplitudes. The school is aimed at PhD students (as well as advanced master students and early postdocs) with a general background in algebra, and with interests in algebra, geometry or topology. There will be three lecture series and extensive problem sessions.
Lecture series
Lara Bossinger : Positive Grassmannians and Cluster algebras
Marcus Spradlin and Anastasia Volovich: Scattering amplitudes and Amplituhedra, mathematical aspects of quantum field theory.
Notes of first lecture. Notes-of-Volovich Exercises
Simon Telen: Positive geometry and canonical forms
