度量Clifford代数

Metric Clifford Algebra

V. V. Fernández, A. M. Moya, W. A. Rodrigues

摘要:

本文引入了度量Clifford代数$\mathcal{C\ell}(V,g)$的概念,其中$n$维实向量空间$V$被赋予了一个度量扩张子$g$,其签名为$(p,q)$,具有$p+q=n$ . $\mathcal{C\ell}(V,g)$上的度量Clifford积表现为$\mathcal{C\ell}(V)$上的欧氏Clifford积的定义良好的\emph{deformation}(由$g$诱导)。与度量伸缩子$g,$相关联的是规范度量伸缩子$h$,其将刚刚包含在$g.$中的所有几何信息编码。这里确定这种$h$的精确形式。此外,我们提出并证明了所谓的\emph{golden formula,},这是很重要的,在许多应用中,自然出现在我们的研究多向量函数,微分几何和理论物理。

英文摘要:

In this paper we introduce the concept of metric Clifford algebra $\mathcal{C\ell}(V,g)$ for a $n$-dimensional real vector space $V$ endowed with a metric extensor $g$ whose signature is $(p,q)$, with $p+q=n$. The metric Clifford product on $\mathcal{C\ell}(V,g)$ appears as a well-defined \emph{deformation}(induced by $g$) of an euclidean Clifford product on $\mathcal{C\ell}(V)$. Associated with the metric extensor $g,$ there is a gauge metric extensor $h$ which codifies all the geometric information just contained in $g.$ The precise form of such $h$ is here determined. Moreover, we present and give a proof of the so-called \emph{golden formula,} which is important in many applications that naturally appear in ours studies of multivector functions, and differential geometry and theoretical physics.
