Generalised Cluster Adjacency for Cosmology
Mattia Capuano, Livia Ferro, Tomasz Lukowski +2
In this paper we study the cluster algebraic properties of wavefunction coefficients for conformally coupled scalar theories in de Sitter cosmology. We show that the symbol of the…

Cosmology meets cluster algebra
Mattia Capuano, Livia Ferro, Tomasz Lukowski +1
In this paper we explore the mathematical properties of wavefunction coefficients in power-law FRW cosmologies, and establish their relation to cluster algebras. We focus on the pa…

Canonical Differential Equations for Cosmology from Positive Geometries
Mattia Capuano, Livia Ferro, Tomasz Lukowski +1
Cosmological correlation functions are central observables in modern cosmology, as they encode properties of the early universe. In this paper, we derive novel canonical differenti…
