A mathematical perspective on nonplanar on-shell forms

Artyom Lisitsyn, Elizabeth Pratt, Melissa Sherman-Bennett +1

On-shell forms are differential forms on the Grassmannian which arise in particle physics. They are defined using bipartite graphs with $n$ distinguished ``boundary'' vertices. Mat…

Combinatorics of $m = 1$ Grasstopes

Yelena Mandelshtam, Dmitrii Pavlov, Elizabeth Pratt

A Grasstope is the image of the totally nonnegative Grassmannian $Gr_{\geq 0} (k, n)$ under a linear map $Gr (k, n) ⇢ Gr (k, k + m)$ . This is a generaliza…
