A Graphical Coaction for FRW Integrals from Partial/Relative Twisted (Co)homology
Andrew J. McLeod, Andrzej Pokraka, Lecheng Ren
We construct a graphical coaction for Friedmann-Robertson-Walker (FRW) integrals at all loop orders in conformally-coupled scalar theories with non-conformal polynomial interaction…

A Graphical Coaction for FRW Wavefunction Coefficients
Andrew McLeod, Andrzej Pokraka, Lecheng Ren
We show that the wavefunction of the universe in theories of conformally coupled scalars in power-law Friedmann-Robertson-Walker (FRW) cosmologies satisfies a graphical coaction, b…
