Singularities of massless scattering and cluster algebras
Lara Bossinger, James Drummond, Ross Glew +2
Partial flag varieties arise in the context of massless scattering kinematics. They can be associated to both spinor-helicity variables and momentum twistor variables in two separa…

Cluster structures on spinor helicity and momentum twistor varieties
Lara Bossinger, Jian-Rong Li
We study the homogeneous coordinate rings of partial flag varieties and Grassmannians in their Plücker embeddings and exhibit an embedding of the former into the latter. Both ring…
