Geometric multipliers and partial teleparallelism in Poincaré gauge theory

نویسندگان

چکیده

The dynamics of the torsion-powered teleparallel theory are only viable because 36 multiplier fields disable all components Riemann-Cartan curvature. We generalize this suggestive approach by considering Poincar\'e gauge in which 60 such ``geometric multipliers'' can be invoked to any given irreducible part curvature, or indeed torsion. Torsion theories motivated a weak-field analysis frequently suffer from unwanted strong-field regime, as activation ghosts. By propagation massive, parity-even vector torsion, we explore how geometric multipliers may able limit departures Hamiltonian constraint structure and consider their tree-level phenomena.

0 Hamiltonian structure and gauge symmetries of Poincaré gauge theory ∗

This is a review of the constrained dynamical structure of Poincaré gauge theory which concentrates on the basic canonical and gauge properties of the theory, including the identification of constraints, gauge symmetries and conservation laws. As an interesting example of the general approach we discuss the teleparallel formulation of general relativity.

Poincaré gauge theory of (2+1)-dimensional gravity.

A Poincaré gauge theory of (2+1)-dimensional gravity is developed. Fundamental gravitational field variables are dreibein fields and Lorentz gauge potentials, and the theory is underlain with the Riemann-Cartan space-time. The most general gravitational Lagrangian density, which is at most quadratic in curvature and torsion tensors and invariant under local Lorentz transformations and under gen...

Gauge Theory and the Geometric Langlands Program

The Langlands program of number theory, or what we might call Langlands duality, was proposed in more or less its present form by Robert Langlands, in the late 1960s. It is a kind of unified scheme for many results in number theory ranging from quadratic reciprocity, which is hundreds of years old, to modern results such as Andrew Wiles’ proof of Fermat’s last theorem, which involved a sort of ...

Noncommutative Geometric Gauge Theory from Superconnections

Noncommutative geometric gauge theory is reconstructed based on the superconnection concept. The bosonic action of the Connes-Lott model including the symmetry breaking Higgs sector is obtained by using a new generalized derivative, which consists of the usual 1-form exterior derivative plus an extra element called the matrix derivative, for the curvatures. We first derive the matrix derivative...

Gauge Theory Gravity with Geometric Calculus

A new gauge theory of gravity on flat spacetime has recently been developed by Lasenby, Doran, and Gull. Einstein’s principles of equivalence and general relativity are replaced by gauge principles asserting, respectively, local rotation and global displacement gauge invariance. A new unitary formulation of Einstein’s tensor illuminates long-standing problems with energy-momentum conservation i...
