Scattering Amplitudes on Riemann Surfaces
Riemann surfaces are ubiquitous for a geometrical description of scattering amplitudes of particles. In particular their symmetries become simple manifestations of properties of complex analysis. As an example we will discuss relations between gauge and gravitational amplitudes by analyzing world-sheet properties of closed and open strings. Link: https://uw-edu-pl.zoom.us/j/92154293299
