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 distinguished ``boundary'' vertices. Mat…
Log Canonical Models and Positive Geometries
Benjamin Hollering, Dmitrii Pavlov, Elizabeth Pratt
Constructing log canonical compactifications of open varieties is a central problem in birational geometry. Finding a natural coordinate system and obtaining the equations of these…
Combinatorics of Grasstopes
Yelena Mandelshtam, Dmitrii Pavlov, Elizabeth Pratt
A Grasstope is the image of the totally nonnegative Grassmannian under a linear map . This is a generaliza…
-Module Techniques for Solving Differential Equations in the Context of Feynman Integrals
Johannes Henn, Elizabeth Pratt, Anna-Laura Sattelberger +1
Feynman integrals are solutions to linear partial differential equations with polynomial coefficients. Using a triangle integral with general exponents as a case in point, we compa…
On The Geometry Of Elliptic Pairs
Elizabeth Pratt
An elliptic pair is a projective rational surface with log terminal singularities, and an irreducible curve contained in the smooth locus of , with arithmetic g…
