Constraining Conformal Correlators
Viktoriia Borovik, Claire de Korte, Nathan Meurrens +1
We study the space of conformally covariant -point functions of spinning operators using methods from invariant theory, commutative algebra, and combinatorics. We show that the…

Cosmological Weight-Shifting Matrices
Claire de Korte, Harry Goodhew, Kamran Salehi Vaziri +1
We construct matrices that shift the scaling dimension of scalar fields for arbitrary de Sitter Feynman diagrams. Acting on a set of master integrals, these weight-shifting matrice…

Partial fraction decompositions on hyperplane arrangements
Claire de Korte, Teresa Yu
We study partial fraction decompositions (PFDs) in several variables using tools from commutative algebra. We give criteria for when a rational function with poles on a hyperplane…
