Quadratic exchange equations for Coxeter matroids
Kieran Calvert, Aram Dermenjian, Alex Fink +1
Tropicalisation (with trivial coefficients) is a process that turns a polynomial equation into a combinatorial predicate on subsets of the set of variables. We show that for each m…

The -fold circuit property for matroids
Bill Jackson, Anthony Nixon, Ben Smith
Double circuits were introduced by Lovász in 1980 as a fundamental tool in his derivation of a min-max formula for the size of a maximum matching in linear matroids. This formula w…

Allowed Coulomb branch scaling dimensions of four-dimensional SCFTs
Philip C. Argyres, Sergio Cecotti, Michele Del Zotto +3
A basic datum of a rank- superconformal field theory (SCFT) is the -tuple of its Coulomb branch scaling dimensions, i.e., the scaling dimensions of a set of…
