Algebraic Approaches to Cosmological Integrals
Cosmological correlators encode statistical properties of the initial conditions of our
universe. Mathematically, they can often be written as Mellin integrals of a certain rational …

We investigate Mellin integrals of products of hyperplanes, raised to an individual power
each. We refer to the resulting functions as combinatorial correlators. We investigate their …
