Spinor algebra transformations as gauge symmetry : limit to Einstein gravity
We construct a Lagrangian of Weyl spinors and gauge fields, which is invariant under the action of equivalent local transformations on the spinor algebra representations. A model of vacuum with a nontrivial gauge strength-tensor setting a scale is suggested, so that the leading approximation at low energies is described by the Einstein–Hilbert Lagrangian of gravity. We consider a mechanism for ...
متن کاملGauge transformations and quasitriangularity
Natural conditions on a Poisson/quantum group G to implement Poisson/quantum gauge transformations on the lattice are investigated. In addition to our previous result that transformations on one lattice link require G to be coboundary, it is shown that for a sequence of links one needs a quasitriangular G. 0 Introduction: one link results Is it possible to formulate lattice (group valued) gauge...
متن کاملMirror Symmetry as a Gauge Symmetry
It is shown that in string theory mirror duality is a gauge symmetry (a Weyl transformation) in the moduli space of N = 2 backgrounds on group manifolds, and we conjecture on the possible generalization to other backgrounds, such as CalabiYau manifolds. e-mail address: [email protected] e-mail address: [email protected]
متن کاملNoncommutativity vs gauge symmetry
In many aspects the most complicated foliated manifolds are those with nonvanishing Godbillon-Vey class. We argue that they probably do not appear in physics and that is due to gauge symmetry which prevents the foliation from becoming “too wild”; that means that the foliation does not develop resilient leaves which, at least in codim-1, by Duminy’s theorem are responsible for the nontriviality ...
متن کاملHidden Gauge Symmetry
In the four dimensional free fermionic formulation of the heterotic string, a semi-realistic SU(4) × SU(2) L × SU(2) R model is proposed with three fermion generations in (4, 2, 1) + (¯ 4, 1, 2) representations. The gauge symmetry of the model breaks to the standard gauge group using a higgs pair in the (4, 1, 2)+(¯ 4, 1, 2) representations. The massless spectrum includes exotic fractionally ch...
