An algorithm to construct the Le diagram associated to a Grassmann necklace

Susama Agarwala, Sian Fryer

Le diagrams and Grassmann necklaces both index the collection of positroids in the nonnegative Grassmannian $G r_{\geq 0} (k, n)$ , but they excel at very different tasks: for example,…

A study in $G_{R, \geq 0}$ : from the geometric case book of Wilson loop diagrams and SYM $N = 4$

Susama Agarwala, Sian Fryer

We study the geometry underlying the Wilson loop diagram approach to calculating scattering amplitudes in the gauge theory of Supersymmetric Yang Mills (SYM) $N = 4$ . By applying the…

Color Lie rings and PBW deformations of skew group algebras

S. Fryer, T. Kanstrup, E. Kirkman +2

We investigate color Lie rings over finite group algebras and their universal enveloping algebras. We exhibit these universal enveloping algebras as PBW deformations of skew group…
