About this document
∆-Algebra in Scattering Amplitudes by polick is a document available to read on EtoBox.
This document introduces an algebra called the ∆-algebra that combines two operations used in scattering amplitudes: computing volumes of polytopes using triangulations and constructing canonical forms from products of smaller ones. It focuses on the case of G(2,n) which controls MHV leading singularities and CHY integrands. The ∆-algebra has three properties: ∆ objects are nilpotent, commute, and can be used to define leading singularities as Grassmann integrals. As an application, the ∆-algebra allows gen
