Abstract: We extend the disformal transformation to models with two scalar fields and look at its singular limit. Solving the eigentensor equation for the Jacobian of the transformation of the metrics we find the two-field extension… read more here.

Abstract: We study thermodynamics in f(R) gravity with the disformal transformation. The transformation applied to the matter Lagrangian has the form of γμν=A(ϕ,X)gμν+B(ϕ,X)∂μϕ∂νϕ with the assumption of the Minkowski matter metric γμν=ημν, where ϕ is the… read more here.
