Noether identities and gauge fixing the action for cosmological perturbations

50 The goal is to help people to reach an optimum level in the dimensions of psychological well- being: environmental mastery, personal growth, purpose in life,

In the previous sections we have shown how astronomical alignments and solar hierophanies – with a common interest in the solstices − were substantiated in the

It is for this reason that we are able to calculate all of the parameters and functions of the emergent theory: the gauge group and the matter content; the Yukawa couplings and

The first cases are particularly simple situations with one or two degrees of freedom for which the exact quantum evolution can be obtained through the numerical integra- tion of

To do that, we have introduced, for both the case of trivial and non-trivial ’t Hooft non-abelian flux, the back- ground symmetric gauge: the gauge in which the stable SU (N )

Derived by requiring gauge invariance and agreement with perturbative computations in the so-called quasi-multi-Regge kinematics, this action encompasses by construction the

The possibility of non-trivial representations of the gauge group on wavefunc- tionals of a gauge invariant quantum field theory leads to a generation of mass for intermediate

These algebras naturally appear as a residual gauge symmetry in the theory of relativistic membranes [3], which exhibits an intriguing connection with the quantum mechanics of
