    “…After an introduction to field theories and the variational approach, individual sections focus on the variational approach in relation to special relativity, general relativity, and alternative theories of gravity. Throughout the text, solved exercises and examples are presented. …”

    Publicado 2019
    “…It is the first detailed exposition of asymptotic safety, providing a unique introduction to quantum gravity and it assumes no previous familiarity with the renormalization group. …”

    “…In particular, we concentrate on two such theories -- the $G/H$ coset models and $2d$ gravity coupled to $c\leq 1$ conformal matter. (to appear in the proceedings of the XXV Karpacz Winter School)…”

    “…The goal of this monograph is to prove that any solution of the Cauchy problem for the capillary-gravity water waves equations, in one space dimension, with periodic, even in space, small and smooth enough initial data, is almost globally defined in time on Sobolev spaces, provided the gravity-capillarity parameters are taken outside an exceptional subset of zero measure. …”

    “…--HTML-->Recent work has shown that pure R^2 gravity (i.e. R^2 gravity with no extra R term) has a symmetry that is larger than scale symmetry and smaller than full Weyl symmetry. …”

    “…Recently a block spin renormalization group approach was proposed for the dynamical triangulation formulation of two-dimensional quantum gravity. We use this approach to examine non-perturbatively a particular class of higher derivative actions for pure gravity.…”

    “…We compute the renormalization group running of the Newton constant and the parameter λ in (3+1)-dimensional projectable Hořava gravity. We use the background-field method, expanding around configurations with flat spatial metric, but nonvanishing shift. …”

    por Bonnefoy, Quentin
    Publicado 2019
    “…--HTML-->I will discuss tests of the weak gravity conjecture in the presence of supersymmetry breaking, using type I string theory with supersymmetry broken by compactification (à la Scherk-Schwarz). …”
