He uses this argument basically to justify that any quantum theory at low energies will be an (effective) field theory. 物理學中，勞侖茲協變性（英語： Lorentz covariance ）是時空的一個關鍵性質，出自於狹義相對論，適用於全域性的場合。局域勞侖茲協變性（英語： Local Lorentz covariance ）所指為僅「局域」於各點附近無限小時空區域的勞侖茲協變性，此則出於廣義相對論。勞侖茲協變性有兩個不同、但緊密關聯的意義：一個物理量要稱為「勞侖茲協變的」（Lorentz covariant），則其是在勞侖茲群的表象下做變換。根據勞侖茲群的表象理論，這些量是以下述的量來建立的：純量、四維矢量、 4-張量與旋量。. . They share with CGS-Gaussian units the property that the electric constant ε 0 and magnetic constant µ 0 do not appear, having been incorporated implicitly into the electromagnetic quantities by the way. . In the 1890s, Lorentz, Wiechert, and Larmor assumed a strictly stationary ether in which atoms, ions, and electrons freely circulated, with field-mediated interactions regulated by the Maxwell-Lorentz equations. In other words, the Lorentz transformation does not dilate the plane of the boost.

Web. In this chapter, we will review previous tests of Lorentz invariance, particularly in the field of electrodynamics. As far as I understand, one requires that in order for the scalar product between two vectors to be invariant under Lorentz transformations xμ → xμ = Λμαxα, we require that the metric ημν transform as ημν → ημ ν = Λαμ ηαβΛβν. . On an example of Nambu-Goto string theory in 4-dimensional Minkowski space-time the idea can be demonstrated as follows: Light cone gauge.

Now to show Lorentz invariance under this special case of rotation around z axis, we just need to show that ( x ′) 2 + ( y ′) 2 = ( x) 2 + ( y) 2, which is trivial.

Si l'on change de référentiel, le changement de coordonnées classique ne s'applique pas aux équations de Maxwell, il faut utiliser une autre transformation : la transformation de Lorentz. . The Schrodinger equation is not Lorentz Invariant, so it cannot be applied to the wave functions of moving particles. Hence that means the postulate of existence of a constant finite speed (that turns out to be equal to the speed of the light in the vacuum) invariant. Minkowski-Raumzeit[edit].

This implies that each part separately is invariant under the Lorentz transformation.
