Gauge freedom in orbital mechanics.
Both orbital and attitude dynamics employ the method of variation of parameters. In a non-perturbed setting, the coordinates (or the Euler angles) are expressed as functions of the time and six adjustable constants called elements. Under disturbance, each such expression becomes ansatz, the "constants" being endowed with time dependence. The perturbed velocity (linear or angular) consists of a ...
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 کاملGauge 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 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 ...
