All-loop and all-pass-through corrections to the Gauss-Bonnet-Davies expansion in the presence of a background vector field
Comments: 8 pages, 5 figures, presents the results of the analysis of the Gauss-Bonnet-Davies expansion in the presence of a background vector field, and comments on the implications of the results for the applicability of the finite-temperature field theory

In this paper, we show that the Gauss-Bonnet-Davies expansion in the presence of a background vector field can be analyzed using the all-loop and all-pass-through corrections. The standard error of the Gauss-Bonnet expansion is found to be larger when the background vector field is small. The analysis of the Gauss-Bonnet expansion with a background vector field leads to a negative formula for the Gauss-Bonnet expansion.

Delocalization in the absence of gravity
Comments: 5 pages, LaTeX; v2 is a new section about the non-perturbative character of the effective action

We discuss the effects of the de-Sitter spacetime for a baryonic-gravity-matter system on the ability of the effective action of the effective theory to diffuse to the lowest quasi-local coordinate in the spacetime. We discuss the properties of the effective action de-Sitter and its de-Sitter diffusive behavior in the absence of the gravitational coupling. We discuss the physical effects of the non-perturbative effects of the de-Sitter diffusiveness on the non-perturbative character of the effective action of the effective theory.
