Einstein-Cartan-Dirac场的二旋量四分体和Lie导数

Two-spinor tetrad and Lie derivatives of Einstein-Cartan-Dirac fields

Daniel Canarutto

摘要:

本文提出了一种旋量、旋量连接和引力场的李导数的综合方法,该方法是在先前提出的基于“最小几何数据”的爱因斯坦-Carta-麦克斯韦-狄拉克场理论的部分原始公式的背景下提出的:所有所需的基本结构都是从具有二维纤维的复向量场$S\to M$的唯一假设中几何构造的。所有考虑类型的对象关于向量场$X:M\to TM$的Lie导数都是定义良好的,而不对$X$作任何特殊的假设,并且满足自然的相互关系。

英文摘要:

An integrated approach to Lie derivatives of spinors, spinor connections and the gravitational field is presented, in the context of a previously proposed, partly original formulation of a theory of Einstein-Carta-Maxwell-Dirac fields based on "minimal geometric data": all the needed underlying structure is geometrically constructed from the unique assumption of a complex vector field $S\to M$ with 2-dimensional fibers. The Lie derivatives of objects of all considered types, with respect to a vector field $X:M\to TM$, are well-defined without making any special assumption about $X$, and fulfill natural mutual relations.
