A bstract The surface charge algebra of generic asymptotically locally (A) dS 4 spacetimes
without matter is derived without assuming any boundary conditions. Surface charges …

We argue that, in a theory of quantum gravity in a four dimensional asymptotically flat
spacetime, all information about massless excitations can be obtained from an infinitesimal …

We present a detailed analysis of gravity in a partial Bondi gauge, where only the three
conditions $ g_ {rr}= 0= g_ {rA} $ are fixed. We relax in particular the so-called determinant …

Using the dictionary between Bondi and Fefferman–Graham gauges, we identify the
analogues of the Bondi news, Bondi mass and Bondi angular momentum aspects at the …

We formulate a holographic Wilsonian renormalization group flow for strongly coupled
systems with a gravity dual, motivated by the need to extract efficiently low energy behavior …

We develop a general framework for constructing charges associated with diffeomorphisms
in gravitational theories using covariant phase space techniques. This framework …

A bstract We construct the holographic dictionary for both running and constant dilaton
solutions of the two dimensional Einstein-Maxwell-Dilaton theory that is obtained by a circle …

These notes are a transcript of lectures given by the author in the XVIII Modave summer
school in mathematical physics. The introduction is devoted to a detailed review of the …

A bstract We study rotating black holes in five dimensions using the nAdS 2/nCFT 1
correspondence. A consistent truncation of pure Einstein gravity (with a cosmological …

As a top-down holographic approach, the D4/D8 model is expected to be a holographic
version of QCD, since it almost includes all the elementary features of QCD based on string …
