并且可用于生成一个具有 的克利福德代数。这样的克利福德代数具有 维数。若试图用一组矩阵表示这个代数,最低可能的阶结果是 个矩阵。这些矩阵所作用的向量性量 被称为 旋量(spinor);它们至少有四个分量,这一事实与相对论性自旋的概念有关。对狄拉克理论的最大检验是对称为正电子的反粒子的预言,安德森于1932年通过实验证明了其存在。

and can be used to generate a Clifford algebra with . Such a Clifford algebra has dimensions. If one attempts to represent this algebra by a set of matrices, the lowest possible order turns out to be matrices. The vectorial quantities on which these matrices act are known as spinors; they have at least four components, a fact related to the concept of relativistic spin. The greatest test for Dirac’s theory was the prediction of antiparticles known as positrons, shown to exist experimentally by Anderson in 1932.
