On the inversion of Noether's theorem in the Lagrangian formalism: II.—Classical field theory
(1970-01-01)
Both the «direct» and the «inverse» Noether's theorems are generalized to allow for infinitesimal transformations that add to the action functional an integral over a 4-divergence and an integral over a function vanishing ...
Conserved quantities in the variational equations

Constraining generalized non-local cosmology from Noether symmetries
(2017)
We study a generalized non-local theory of gravity which, in specific limits, can become either the curvature non-local or teleparallel non-local theory. Using the Noether symmetry approach, we find that the coupling ...
Formalismo de Hamilton-Jacobi generalizado: teorias de campos com derivadas de ordem superior
(Universidade Estadual Paulista (Unesp), 2010-04-30)
Neste trabalho apresentaremos o formalismo de Hamilton-Jacobi para sistemas singulares em teorias de campos, com foco em teorias com derivadas de ordem superior. Iniciaremos com uma análise preliminar do cálculo variacional ...
Parity singlets and doublets of massive spin-3 particles in D = 2 + 1 via Noether gauge embedding
(2019-08-01)
Here we demonstrate that the sixth-order (in derivatives) spin-3 self-dual model can be obtained from the fifth-order self-dual model via a Noether Gauge Embedding (NGE) of longitudinal Weyl transformations η( μ ν∂α )Φ. ...
Dual descriptions of massive spin-3 particles in D=2+1 via Noether gauge embedment
(Amer Physical Soc, 2015-03-31)
We present here a relationship among massive self-dual models for spin-3 particles in D = 2 + 1 via the Noether gauge embedment (NGE) procedure. Starting with a first-order model (in derivatives) S-SD(1) we have obtained ...
