چکیده
We revisit the issue that Noether current associated with a local scale symmetry, or equivalently Weyl identically vanishes. Based on only second theorem for we prove symmetry is in general vanishing any invariant gravitational theories four-dimensional Riemannian geometry. also clarify reason: The transformation nondynamical sense it does not contain derivative term of parameter as opposed to conventional gauge transformation.

The Noether Number in Invariant Theory
Let F be any field. Let G be any reductive linear algebraic group and consider a finite dimensional rational representation V of G. Then the Falgebra F[V ] of polynomial invariants for G acting on V is finitely generated. The Noether Number β(G,V ) is the highest degree of an element of a minimal homogeneous generating set for F[V ]. We survey what is known about Noether Numbers, in particular ...
متن کاملRadiating Collapse with Vanishing Weyl stresses
In a recent approach in modelling a radiating relativistic star undergoing gravitational collapse the role of the Weyl stresses was emphasised. It is possible to generate a model which is physically reasonable by approximately solving the junction conditions at the boundary of the star. In this paper we demonstrate that it is possible to solve the Einstein field equations and the junction condi...
متن کاملThermodynamic Entropy as a Noether Invariant.
We study a classical many-particle system with an external control represented by a time-dependent extensive parameter in a Lagrangian. We show that thermodynamic entropy of the system is uniquely characterized as the Noether invariant associated with a symmetry for an infinitesimal nonuniform time translation t→t+ηℏβ, where η is a small parameter, ℏ is the Planck constant, β is the inverse tem...
متن کاملBlack Hole Mass Formula Is a Vanishing Noether Charge
The Noether current and its variation relation with respect to diffeomorphism invariance of gravitational theories have been derived from the horizontal variation and vertical-horizontal bi-variation of the Lagrangian, respectively. For Einstein’s GR in the stationary, axisymmetric black holes, the mass formula in vacuum can be derived from this Noether current although it definitely vanishes. ...
متن کاملThe Noether-lefschetz Theorem via Vanishing of Coherent Cohomology
We prove that for a generic hypersurface in P of degree at least 2 + 2/n, the n-th Picard number is one. The proof is algebraic in nature and follows from certain coherent cohomology vanishing.
