Regularized dualities in patch cosmology
Gianluca Calcagni
Following past investigations, we explore the symmetries of the Hamilton-Jacobi cosmological equations in the generalized patch formalism describing braneworld and tachyon scenario…

Patch dualities and remarks on nonstandard cosmologies
Gianluca Calcagni
In this paper we establish dualities between inflationary, cyclic/ekpyrotic, and phantom cosmologies within the patch formalism approximating high-energy effects in scenarios with…
