Noether Currents and Generators of Local Gauge Transformations in the Covariant Canonical Formalism

نویسندگان

چکیده

We investigate generators of local transformations in the covariant canonical formalism (CCF). The CCF treats space and time on an equal footing regarding differential forms as basic variables. conjugate $\pi_A$ are defined derivatives Lagrangian $d$-form $L(\psi^A, d\psi^A)$ with respect to $d\psi^A$, namely $\pi_A := \partial L/\partial d\psi^A$, where $\psi^A $ $p$-form dynamical fields. form-canonical equations derived from form-Legendre transformation form $H:=d\psi^A \wedge \pi_A - L$. show that Noether current is generator infinitesimal \to \psi^A + \delta \psi^A$ if given by $\delta L=dl$ $l$ depend only $\psi^A$ parameters. As instance, we study gauge for field Lorentz second order gravity.

Moufang transformations and Noether currents

The Noether currents generated by continuous Moufang tranformations are constructed and their equal-time commutators are found. The corresponding charge algebra turns out to be a birepresentation of the tangent Mal’ltsev algebra of an analytic Moufang loop.

Conserved Noether Currents, Utiyama’s Theory of Invariant Variation, and Velocity Dependence in Local Gauge Invariance

The paper discusses the mathematical consequences of the application of derived variables in gauge fields. Physics is aware of several phenomena, which depend first of all on velocities (like e.g., the force caused by charges moving in a magnetic field, or the Lorentz transformation). Applying the property of the second Noether theorem, that allowed generalised variables, this paper extends the...

Gauge Symmetries and Noether Currents in Optimal Control

Abstract. We extend the second Noether theorem to optimal control problems which are invariant under symmetries depending upon k arbitrary functions of the independent variable and their derivatives up to some order m. As far as we consider a semi-invariance notion, and the transformation group may also depend on the control variables, the result is new even in the classical context of the calc...

Canonical Transformations and Gauge Fixing in the Triplectic Quantization

We show that the generators of canonical transformations in the triplectic manifold must satisfy constraints that have no parallel in the usual field antifield quantization. A general form for these transformations is presented. Then we consider gauge fixing by means of canonical transformations in this Sp(2) covariant scheme, finding a relation between generators and gauge fixing functions. Th...

Manifestly covariant canonical quantization II: Gauge theory and anomalies

In hep-th/0411028 a new manifestly covariant canonical quantization method was developed. The idea is to quantize in the phase space of arbitrary histories first, and impose dynamics as first-class constraints afterwards. The Hamiltonian is defined covariantly as the generator of rigid translations of the fields relative to the observer. This formalism is now applied to theories with gauge symm...
