Model spaces as constrained Hamiltonian systems. Part I. Application to SU(2)

Journal of High Energy Physics
Motivated by group-theoretical questions that arise in the context of asymptotic symmetries in gravity, we study model spaces and their quantization from the viewpoint of constrained Hamiltonian systems. More precisely, we propose that a central building

The holography of the 2D inhomogeneously deformed CFT

Journal of High Energy Physics
We systematically study inhomogeneous Hamiltonians in two-dimensional conformal field theories within the framework of the AdS/CFT correspondence by relating them to two-dimensional curved backgrounds.

Coadjoint orbits of the Virasoro group [PDF]

Communications in Mathematical Physics, 1988
The coadjoint orbits of the Virasoro group, which have been investigated by Lazutkin and Pankratova and by Segal, should according to the Kirillov-Kostant theory be related to the unitary representations of the Virasoro group. In this paper, the classification of orbits is reconsidered, with an explicit description of the possible centralizers of ...

Symplectic actions on coadjoint orbits

Physics Letters B, 1990
Abstract We present a compact expression for the field theoretical actions based on the symplectic analysis of coadjoint orbits of Lie groups. The final formula for the action density αc becomes a bilinear form 〈(S, 1/λ), (y, my)〈, where S is a 1-cocycle of the Lie group (a schwarzian type of derivative in conformal case), λ is a coefficient of the ...

Geometric Structures on Spaces of Weighted Submanifolds

Symmetry, Integrability and Geometry: Methods and Applications, 2009
In this paper we use a diffeo-geometric framework based on manifolds that are locally modeled on ''convenient'' vector spaces to study the geometry of some infinite dimensional spaces.

Towards complexity of primary-deformed Virasoro circuits

Journal of High Energy Physics
The Fubini-Study metric is a central element of information geometry. We explore the role played by information geometry for determining the circuit complexity of Virasoro circuits and their deformations. To this effect, we study unitary quantum circuits

Contact 4d Chern-Simons theory: generalities

Journal of High Energy Physics
We refine and generalize the results of [1], where evidence in favor of applying the non-Abelian localization method to handle the 4d Chern-Simons theory path integral formulation was presented.

The Restricted Siegel Disc as Coadjoint Orbit

The restricted Siegel disc is a homogeneous space related to the connected component $T_0(1)$ of the Universal Teichmüller space via the period mapping. In this paper we show that it is a coadjoint orbit of the universal central extension of the restricted symplectic group or, equivalently, an affine coadjoint orbit of the restricted symplectic group ...
