By the more narrow definition, commonly used in mathematics, the term Killing spinor indicates those twistor spinors which are also eigenspinors of the Dirac operator. The term is named after Wilhelm Killing. Another equivalent definition is that Killing spinors are the solutions to the Killing equation for a so-called Killing number. More formally:〔 〕 :A Killing spinor on a Riemannian spin manifold ''M'' is a spinor field $\backslash psi$ which satisfies ::$\backslash nabla\_X\backslash psi=\backslash lambda\; X\backslash cdot\backslash psi$ :for all tangent vectors ''X'', where $\backslash nabla$ is the spinor covariant derivative, $\backslash cdot$ is Clifford multiplication and $\backslash lambda$ is a constant, called the Killing number of $\backslash psi\backslash ,$. If $\backslash lambda=0$ then the spinor is called a parallel spinor. In physics, Killing spinors are used in supergravity and superstring theory, in particular for finding solutions which preserve some supersymmetry. They are a special kind of spinor field related to Killing vector fields and Killing tensors. ==References== 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「Killing spinor」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.
