This 20-minute talk explores Matter-Chern–Simons theory on S^2 x S^1 at large-N in the 'temporal' gauge, presented by Vatsal at the International Centre for Theoretical Sciences. Learn about this complex theoretical physics topic as part of the "Positive Geometry in Scattering Amplitudes and Cosmological Correlators" program. The program brings together experts from mathematical aspects of scattering amplitudes and cosmology, exploring connections between perturbative on-shell scattering amplitudes and cosmological correlators. Discover how recent developments in unitarity methods, recursion relations, worldsheet models, bootstrap methods, and connections to positive geometry are pushing toward a reformulation of the perturbative S-matrix using new principles. The talk contributes to the broader workshop goal of advancing connections between these seemingly different fields of theoretical physics.
