Gauge Symmetry and Gravito-electromagnetism
A tensor description of perturbative Einsteinian gravity about an arbitrary background spacetime is developed. By analogy with the covariant laws of electromagnetism in spacetime, gravito-electromagnetic potentials are defined to emulate the gauge transformations of electromagnetic potentials under substitutions belonging to the gauge symmetry group of perturbative gravitation. These definition...
متن کاملGravito-Electromagnetism (GEM) Weak (Linearizable) Slowly Changing Gravitation
Instead of imagining space-time as being warped by mass and energy, one can speak of a classical spin-2 graviton field (in flat, Minkowski space-time) that generates gravitation. Although we don’t know yet how to quantize this field, we can think of it in a way similar to how we think of electromagnetism being mediated by photons. And just as a 1/r2 Coulomb force generates magnetism when the fi...
متن کاملGauge Symmetry and Neural Networks
We propose a new model of neural network. It consists of spin variables to describe the state of neurons as in the Hopfield model and new gauge variables to describe the state of synapses. The model possesses local gauge symmetry and resembles lattice gauge theory of high-energy physics. Time dependence of synapses describes the process of learning. The mean field theory predicts a new phase co...
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 ...
