A bstract The SYK model is a quantum mechanical model that has been proposed to be
holographically dual to a 1+ 1-dimensional model of a quantum black hole. An emergent …

A bstract We rewrite the Chern-Simons description of pure gravity on global AdS 3 and on
Euclidean BTZ black holes as a quantum field theory on the AdS boundary. The resulting …

A bstract We study aspects of Jackiw-Teitelboim (JT) quantum gravity in two-dimensional
nearly de Sitter (dS) spacetime, as well as pure de Sitter quantum gravity in three …

Now in paperback, this book provides a self-contained introduction to the cohomology
theory of Lie groups and algebras and to some of its applications in physics. No previous …

This book is an introduction to the role of topology in the quantization of classical systems. It
is also an introduction to topological solitons with special emphasis on Skyrmions. As …

A bstract The constrained Hamiltonian analysis of geometric actions is worked out before
applying the construction to the extended Bondi-Metzner-Sachs group in four dimensions …

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 …

The solution space of three-dimensional asymptotically anti-de Sitter or flat Einstein gravity
is given by the coadjoint representation of two copies of the Virasoro group in the former and …

A bstract We develop the gauge theory formulation of\(\mathcal {N}\)= 1 Jackiw-Teitelboim
supergravity in terms of the underlying OSp (1| 2, ℝ) supergroup, focusing on boundary …
