Global symmetries require conservation laws, but not forces, in physics. An example of a global symmetry is the action of the $U(1)=e^$ (for $\backslash theta$ a constant - making it a global transformation) group on the Dirac Lagrangian: ::$\backslash mathcal\_D\; =\; \backslash bar\backslash left(i\backslash gamma^\backslash mu\; \backslash partial\_\backslash mu-m\backslash right)\backslash psi$ Under this transformation the wavefunction changes as $\backslash psi\backslash rightarrow\; e^\backslash psi$ and $\backslash bar\backslash rightarrow\; e^\backslash bar$ and so: ::$\backslash mathcal\backslash rightarrow\backslash bar\backslash bar\backslash left(i\backslash gamma^\backslash mu\; \backslash partial\_\backslash mu-m\backslash right)e^\backslash psi=e^e^\backslash bar\backslash left(i\backslash gamma^\backslash mu\; \backslash partial\_\backslash mu-m\backslash right)\backslash psi=\backslash mathcal$ ==See also== *Field (physics) *Global spacetime structure *Local spacetime structure 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Global symmetry」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
