Property Transformations For Translations
When translating a system description from one speciication language to another, it is, in many cases, inevitable that the underlying models of the original and the translated speciication will be diierent. The notion of property transformation can be used to deene the relation between the properties of the original and the translated model. In an earlier paper, deenitions of 'faithful' transla...
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 کاملSpinor 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 کاملWigner’s little group as a generator of gauge transformations
In his paper On unitary representations of the inhomogeneous Lorentz group, published in 1932 [1], Eugene Paul Wigner introduced the concept of little group and used it to classify the elementary particles on the basis of their helicity/spin quantum numbers. The topic of little group was a personal favorite of Prof. Wigner. During the last years of his life, he wrote a series of seven papers in...
متن کاملConformal Gauge Transformations in Thermodynamics
In this work, we show that the thermodynamic phase space is naturally endowed with a non-integrable connection, defined by all of those processes that annihilate the Gibbs one-form, i.e., reversible processes. We argue that such a connection is invariant under re-scalings of the connection one-form, whilst, as a consequence of the non-integrability of the connection, its curvature is not and, t...
