Positive del Pezzo Geometry

Nick Early, Alheydis Geiger, Marta Panizzut +2

Real, complex, and tropical algebraic geometry join forces in a new branch of mathematical physics called positive geometry. We develop the positive geometry of del Pezzo surfaces…

Generalized Color Orderings: CEGM Integrands and Decoupling Identities

Freddy Cachazo, Nick Early, Yong Zhang

In a recent paper, we defined generalized color orderings (GCO) and Feynman diagrams (GFD) to compute color-dressed generalized biadjoint amplitudes. In this work, we study the Cac…
