Cartan Connections and Lie Algebroids

open access: yes, 2009
This paper is a study of the relationship between two constructions associated with Cartan geometries, both of which involve Lie algebroids: the Cartan algebroid, due to [Blaom A.D., Trans. Amer. Math. Soc.

Geometry of Maurer-Cartan varieties [PDF]

open access: yes, 2011
A cada problema de deformación se le asocia un álgebra de Lie diferencial graduada, E. El espacio de móduli asociado al problema de deformación viene dado por la variedad de Maurer-Cartan de E módulo la acción de gauge. Esta tesis se divide en dos partes.

Cartan structure equations and Levi-Civita connection in noncommutative geometry

open access: yes
We study the differential and Riemannian geometry of algebras A endowed with an action of a triangular Hopf algebra H and noncommutativity compatible with the associated braiding.

A new formulation of non-relativistic diffeomorphism invariance

open access: yesPhysics Letters B, 2014
We provide a new formulation of non-relativistic diffeomorphism invariance. It is generated by localising the usual global Galilean symmetry. The correspondence with the type of diffeomorphism invariant models currently in vogue in the theory of ...

Zooming in on AdS3/CFT2 near a BPS bound

open access: yesJournal of High Energy Physics, 2018
Any (d + 1)-dimensional CFT with a U(1) flavor symmetry, a BPS bound and an exactly marginal coupling admits a decoupling limit in which one zooms in on the spectrum close to the bound.

The Toda-Weyl mass spectrum

open access: yesNuclear Physics B
The masses of affine Toda theories are known to correspond to the entries of a Perron-Frobenius eigenvector of the relevant Cartan matrix. The Lagrangian of the theory can be expressed in terms of a suitable eigenvector of a Coxeter element in the Weyl ...

A new look at Newton–Cartan gravity [PDF]

open access: yes, 2016
We give a short overview of Newton–Cartan geometry and gravity including its matter couplings. We also present results on a new non-relativistic gravity model in three spacetime dimensions, called extended Bargmann gravity, and show that this model has ...

Non-Riemannian geometry of M-theory

open access: yesJournal of High Energy Physics, 2019
We construct a background for M-theory that is moduli free. This background is then shown to be related to a topological phase of the E8(8) exceptional field theory (ExFT).

Normal forms in Poisson geometry [PDF]

open access: yes, 2013
The structure of Poisson manifolds is highly nontrivial even locally. The first important result in this direction is Conn's linearization theorem around fixed points. One of the main results of this thesis (Theorem 2) is a normal form theorem in Poisson
