The (non-uniform) Hrushovski-Lang-Weil estimates

Shuddhodan Kadattur Vasudevan

Abstract

In 1996 using techniques from model theory and intersection theory, Hrushovski obtained a generalisation of the Lang-Weil estimates. Subsequently the estimates have found applications in group theory, algebraic dynamics and algebraic geometry. We shall discuss a geometric proof of the non-uniform version of these estimates.

Perturbative gauge theory and 2+2=4

Abstract

Abstract: I shall highlight the repeated occurrence of a certain mathematical structure appearing in different manifestations within the field of scattering amplitudes, thereby acting as a leitmotif. In addition, the representations of tree-level color structures under external leg permutations will be characterised.
