Explorations of Matroid Complexes
Juliette Bruce, Jacob Bucciarelli, Bailee Zacovic
Motivated by Kontsevich's graph complexes, this paper gives a systematic study of matroid complexes. We construct deletion and contraction bicomplexes on the vector space spanned b…

Graphical Scattering Equations
Barbara Betti, Viktoriia Borovik, Bella Finkel +2
The CHY scattering equations on the moduli space play a prominent role at the interface of particle physics and algebraic statistics. We study the scattering corresponden…

Uniqueness of MHV Gravity Amplitudes
Joris Koefler, Umut Oktem, Shruti Paranjape +2
We investigate MHV tree-level gravity amplitudes as defined on the spinor-helicity variety. Unlike their gluon counterparts, the gravity amplitudes do not have logarithmic singular…
