Gravity as universal UV completion: Towards a unified view of Swampland conjectures

Abstract

On the basis of the idea that gravity defines a universal UV-completion and using a form of UV/IR correspondence we revisit some Swampland conjectures, in particular de Sitter and infinite distance conjectures, from the point of view of renormalization group energy flow. The rol and limitations of non perturbative instanton effects to define a metastable cosmological constant are briefly discussed in this context.
