Combinatorics of the Cosmohedron
Federico Ardila-Mantilla, Nima Arkani-Hamed, Carolina Figueiredo +1
The cosmohedron was recently proposed as a polytope underlying the cosmological wavefunction for theory. Its faces were conjectured to be in bijection with Matryos…

Correlator Polytopes
Carolina Figueiredo, Francisco Vazão
Recently, "cosmohedra" have been introduced as polytopes underlying the cosmological wavefunction for conformally coupled Tr() theory in FRW cosmologies, generalizing associah…

Cosmohedra
Nima Arkani-Hamed, Carolina Figueiredo, Francisco Vazão
It has been a long-standing challenge to find a geometric object underlying the cosmological wavefunction for Tr() theory, generalizing associahedra and surfacehedra for scatt…
