lorentz covariance造句

• General relativity postulates that the local Lorentz covariance in the presence of matter.
• :He's talking about Lorentz covariance.
• He corrected some mistakes of Lorentz and proved the Lorentz covariance of the electromagnetic equations.
• Modern formulations of classical field theories generally require Lorentz covariance as this is now recognised as a fundamental aspect of nature.
• "' Local Lorentz covariance "', which follows from general relativity, refers to Lorentz covariance applying only Poincar?covariance and Poincar?invariance.
• "' Local Lorentz covariance "', which follows from general relativity, refers to Lorentz covariance applying only Poincar?covariance and Poincar?invariance.
• It is a Lorentz invariant condition, and is frequently called the " Lorentz condition " because of confusion with Hendrik Lorentz, after whom Lorentz covariance is named.
• Thus, by " deriving " either approach from the other, problems associated with one or the other approach ( as exemplified by Lorentz covariance or unitarity ) go away.
• So by pointing out the group characteristics of the transformation Poincar?demonstrated the Lorentz covariance of the Maxwell Lorentz equations and corrected Lorentz's transformation formulae for charge density and current density.
• The basic structure of general relativity, including the geodesic equation and Einstein field equation, can be obtained from special relativity by examining the symmetry, the transition involves replacing global Lorentz covariance with local Lorentz covariance.
• The basic structure of general relativity, including the geodesic equation and Einstein field equation, can be obtained from special relativity by examining the symmetry, the transition involves replacing global Lorentz covariance with local Lorentz covariance.
• As a consequence, the notion of a complete " special relativistic " theory of gravitation had to be given up, as in general relativity the constancy of light speed ( and Lorentz covariance ) is only locally valid.
• After the full Lorentz covariance formulations that were finite at any order in a perturbation series of quantum electrodynamics, Sin-Itiro Tomonaga, Julian Schwinger and Richard Feynman were jointly awarded with a Nobel prize in physics in 1965.
• This formulation has proven crucial to the subsequent development of theoretical physics, because manifest Lorentz covariance ( time and space components of quantities enters equations in the same way ) is easier to achieve than in the operator formalism of canonical quantization.
• The strength of special relativity lies in its derivation from simple, basic principles, including the invariance of the laws of physics under a shift of inertial reference frames and the invariance of the speed of light in a vacuum . ( See also : Lorentz covariance .)
• Due to the expansion increasing as distances increase, the distance between two remote galaxies can increase at more than 3 m / s, but this does not imply that the galaxies move faster than the speed of light at their present location ( which is forbidden by Lorentz covariance ).
• It is one of the triumphs of comparatively recent years ( ~ 1948 1950 ) that the concepts of Lorentz covariance and gauge invariance were exploited sufficiently cleverly to circumvent these difficulties in quantum electrodynamics and so allow the calculation of very small radiative effects to extremely high precision, in full agreement with experiment.

• This operator occurs in relativistic quantum field theory, such as the Dirac equation and other relativistic wave equations, since energy and momentum combine into the 4-momentum vector above, momentum and energy operators correspond to space and time derivatives, and they need to be first order partial derivatives for Lorentz covariance.
• For example, in the theory of manifolds, each point is contained in a ( by no means unique ) coordinate chart, and this chart can be thought of as representing the'local spacetime'around the local Lorentz covariance, which states that the laws of special relativity hold locally about each point of spacetime, lends further support to the choice of a manifold structure for representing spacetime, as locally around a point on a general manifold, the region'looks like', or approximates very closely Minkowski space ( flat spacetime ).
