Remark on higher-derivative mechanics with l-conformal Galilei symmetry

Based on the results in [A. Galajinsky and I. Masterov, Nucl. Phys. B 866, 212 (2013)], we consider a way to construct a higher-derivative mechanical model which possesses the l-conformal Galilei

Minimal realization of ℓ-conformal Galilei algebra, Pais-Uhlenbeck oscillators and their deformation

We present the minimal realization of the ℓ-conformal Galilei group in 2+1 dimensions on a single complex field. The simplest Lagrangians yield the complex PaisUhlenbeck oscillator equations. We

Hamiltonian formulation for perfect fluid equations with the l-conformal Galilei symmetry

The Hamiltonian formulation for perfect fluid equations with the l-conformal Galilei symmetry is proposed. For an arbitrary half-integer value of the parameter l, the Hamilton and non-canonical

A bstractWe present the minimal realization of the ℓ-conformal Galilei group in 2+1 dimensions on a single complex field. The simplest Lagrangians yield the complex PaisUhlenbeck oscillator

Aspects of infinite dimensional ℓ-super Galilean conformal algebra

In this work, we construct an infinite dimensional l-super Galilean conformal algebra, which is a generalization of the l = 1 algebra found in the literature. We give a classification of central

Taub-NUT as Bertrand spacetime with magnetic fields

Based on symmetries Taub-NUT shares with Bertrand spacetime, we cast it as the latter with magnetic fields. Its nature as a Bianchi-IX gravitational instanton and other related geometrical properties

Conformal Galilei groups, Veronese curves and Newton–Hooke spacetimes

Finite-dimensional nonrelativistic conformal Lie algebras spanned by polynomial vector fields of Galilei spacetime arise if the dynamical exponent is z = 2/N with N = 1, 2, …. Their underlying group

Galilean conformal mechanics from nonlinear realizations

We apply the nonlinear realizations method for constructing new Galilean conformal mechanics models. Our starting point is the Galilean conformal algebra which is a nonrelativistic contraction of its

Metrics with Galilean conformal isometry

The Galilean conformal algebra (GCA) arises in taking the nonrelativistic limit of the symmetries of a relativistic conformal field theory in any dimensions. It is known to be infinite dimensional in

Non-relativistic conformal symmetries and Newton–Cartan structures

This paper provides us with a unifying classification of the conformal infinitesimal symmetries of non-relativistic Newton–Cartan spacetime. The Lie algebras of non-relativistic conformal

Near horizon black holes in diverse dimensions and integrable models

The near horizon geometry of extremal rotating black hole in arbitrary dimension possesses SO(2,1)xU(n) symmetry in the special case that all n rotation parameters are equal. We consider a conformal

Nonrelativistic conformal groups

In this work a systematic study of finite-dimensional nonrelativistic conformal groups is carried out under two complementary points of view. First, the conformal Killing equation is solved to obtain
