超Dirac算子的共形对称性

Conformal symmetries of the super Dirac operator

Kevin Coulembier, Hendrik De Bie

摘要:

本文沿着Stein和Weiss构造广义Cauchy-Riemann算子的思路,定义了作用在超旋量空间中的超函数上的Dirac算子。对称超代数osp(m)的引入|2n)是这种方法的一个新的基本特征。本文将这种对称代数推广到共形对称代数osp(m + 1,1| 2n)。Dirac算子的核作为这两个代数的表示进行了研究。该构造也给出了Howe对偶对osp(1)的一个显式实现|2)x osp(m| 2n)< osp(m + 4n| 2m + 2n)。最后,超狄拉克算子给出了洞察分类不变的一阶微分算子在超抛物几何的开放问题。

英文摘要:

In this paper, the Dirac operator, acting on super functions with values in super spinor space, is defined along the lines of the construction of generalized Cauchy-Riemann operators by Stein and Weiss. The introduction of the superalgebra of symmetries osp(m|2n) is a new and essential feature in this approach. This algebra of symmetries is extended to the algebra of conformal symmetries osp(m + 1, 1|2n). The kernel of the Dirac operator is studied as a representation of both algebras. The construction also gives an explicit realization of the Howe dual pair osp(1|2) x osp(m|2n) < osp(m + 4n|2m + 2n). Finally, the super Dirac operator gives insight into the open problem of classifying invariant first order differential operators in super parabolic geometries.
