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…
Chip-firing and critical groups of signed graphs
Matthew Cho, Anton Dochtermann, Ryota Inagaki +3
We study chip-firing on a signed graph , employing a general theory of chip-firing on invertible matrices introduced by Guzmán and Klivans. Here a negative edge designates an…
Enumerating threshold graphs and some related graph classes
David Galvin, Greyson Wesley, Bailee Zacovic
We give combinatorial proofs of some enumeration formulas involving labelled threshold, quasi-threshold, loop-threshold and quasi-loop-threshold graphs. In each case we count by nu…
