Spontaneously Broken 3d Hietarinta/Maxwell Chern-Simons Theory and Minimal Massive Gravity
Dmitry Chernyavsky, Nihat Sadik Deger, Dmitri Sorokin
We show that minimal massive 3d gravity (MMG), as well as the topological massive gravity, are particular cases of a more general `minimal massive gravity' theory (with a single ma…
Three-dimensional (higher-spin) gravities with extended Schrödinger and -conformal Galilean symmetries
Dmitry Chernyavsky, Dmitri Sorokin
We show that an extended Schrödinger algebra introduced in [1] can be reformulated as a Poincaré algebra extended with an SO(2) R-symmetry generator and an double…
On superconformal mechanics
Dmitry Chernyavsky
Superparticle models with supersymmetry group are studied. We first consider the case and construct the models with -symmetry on the coset spaces of the $OSp(4|…
superconformal mechanics with fermionic gauge symmetry
Dmitry Chernyavsky
We study superpaticle models with fermionic gauge symmetry on the coset spaces of the supergroup. We first construct supersymmetric extension of a particle…
Super 0--brane action on the coset space of supergroup
Dmitry Chernyavsky
The super 0-brane action on the coset space of supergroup is constructed which involves a set of parameters related by -symmetry. It describes a massive superparticle…
Coset spaces and Einstein manifolds with l-conformal Galilei symmetry
Dmitry Chernyavsky
The group theoretic construction is applied to construct a novel dynamical realization of the --conformal Galilei group in terms of geodesic equations on the coset space. A pecu…
Ricci-flat spacetimes with l-conformal Galilei symmetry
D. Chernyavsky, A. Galajinsky
Ricci-flat metrics of the ultrahyperbolic signature which enjoy the l-conformal Galilei symmetry are constructed. They involve the AdS_2-metric in a way similar to the near horizon…
Reducibility of Killing tensors in d>4 NHEK geometry
Dmitry Chernyavsky
An extremal rotating black hole in arbitrary dimension, along with time translations and rotations, possesses a number of hidden symmetries characterized by the second rank Killing…
