The aim of this work is to unveil a striking equivalence between the one-loop divergences in 7D Einstein and 6D conformal gravities.
The particular combination of 6D pointwise Weyl invariants of the 6D conformal gravity corresponds to those of Branson's Q-curvature and can be written solely in terms of the Ricci tensor and its covariant derivatives.
The quadratic metric fluctuations of this...

11. Emergent Universe by Tunneling in a Jordan-Brans-Dicke Theory

Pedro Labraña (UBB)

In this work we study an alternative scheme for an Emergent Universe scenario in the context of a Jordan-Brans-Dicke theory, where the universe is initially in a truly static state supported by a scalar field located in a false vacuum. The model presents a classically stable past eternal static state which is broken when, by quantum tunneling, the scalar field decays into a state of true...

28. Analytical solution to nonsinglet DGLAP}]{Analytical solution to DGLAP integro-differential equation with running gauge coupling

We propose an algorithm to solve DGLAP integro-differential equation analytically in higher orders of the running gauge coupling α with splitting functions given at a fixed order in α. Complex analysis is significantly used in the construction of the algorithm, we found a simpler way to calculate the involved integrals over contours in the complex planes than by any of the well-known methods.
