Contribution

It presents a novel functor-based formalism for field theories, specifically applied to effective theories of large-scale structure in cosmology.

Findings

Offers guidelines for choosing among cosmological models

Abstract

In this document, we introduce a novel formalism for any field theory and apply it to the effective field theories of large-scale structure. The new formalism is based on functors of actions composing those theories. This new formalism predicts the actionic fields. We discuss our findings in a cosmological gravitology framework. We present these results with a cosmological inference approach and give guidelines on how we can choose the best candidate between those models with some latest understanding of model selection using Bayesian inference.
