The Mass Hyperboloid as a Poisson-Lie Group

S. G. Rajeev, Patrizia Vitale

The light cone formalism of a massive scalar field has been shown by Dirac to have many advantages. But it is not manifestly Lorentz invariant. We will show that this is a feature…

Lie Bi-Algebras on the Non-Commutative Torus

Giovanni Landi, S. G. Rajeev

Infinitesimal symmetries of a classical mechanical system are usually described by a Lie algebra acting on the phase space, preserving the Poisson brackets. We propose that a quant…

An Infinitesimal Quantum Group Underlies Classical Fluid Mechanics

S. G. Rajeev

Arnold showed that the Euler equations of an ideal fluid describe geodesics in the Lie algebra of incompressible vector fields. We will show that helicity induces a splitting of th…

Curvature in Hamiltonian Mechanics And The Einstein-Maxwell-Dilaton Action

S. G. Rajeev

Riemannian geometry is a particular case of Hamiltonian mechanics: the orbits of the hamiltonian are the geodesics. Given a symplectic manifold (Γ,ω…

Highly nonlinear wave solutions in a dual to the chiral model

S. G. Rajeev, Evan Ranken

We consider a two-dimensional scalar field theory with a nilpotent current algebra, which is dual to the Principal Chiral Model. The quantum theory is renormalizable and not asympt…
