Title: Gluon Amplitudes on Celestial Sphere/All-loop singularities of scattering amplitudes in massless planar theories

Abstract: There will be two 30 minute talks, back to back.

First talk: TBA

Second talk: I will explain the classification of Landau singularities in
arbitrary massless, planar field theories.
