Abstract: Matroids are combinatorial
abstractions of the notion of linear independence. They are one of
the main objects studied in the current special year in the School
of Mathematics. I will talk about a notion of scattering amplitudes
for...

Abstract: I will discuss a gauge invariant
"memory" observable on cosmological horizons that controls the
existence of (normalizable) de Sitter invariant vacuum states.
While most of the discussion will concern free quantum field
theories, I will...
Abstract: A remarkably simple idea makes
it possible to put global positive coordinates on moduli spaces of
curves. I will give an update on recent developments in
understanding these coordinates and applying them moduli space
integrals. Interesting...
