复射影空间上的广义瞬子

Generalized Instantons on Complex Projective Spaces

Hironobu Kihara, Muneto Nitta

摘要:

在复射影空间上,利用Fubini-Study度量研究了规范理论中的一类广义自对偶关系。我们的理论只包含规范群为U(n)的规范场。我们考虑的伪能量包含更高阶的场强,并由小于或等于[n/2]的整数p标记。为了使Bogomol 'nyi完成,我们需要在伪能量的非单一的跟踪项,不像球上定义的模型,这是以前研究。利用自旋联系的一部分,构造了广义自对偶方程Bogomol 'nyi方程的余维2n的显式解.

英文摘要:

We study a class of generalized self-duality relations in gauge theories on the complex projective space with the Fubini-Study metric. Our theories consist of only gauge fields with gauge group U(n). The pseudo-energies which we consider contain higher orders of field strength and are labeled by an integer p smaller than or equal to [n/2]. For making the Bogomol'nyi completion we need non-single trace terms in the pseudo-energies, unlike the models defined on spheres, which were studied previously. We construct an explicit solution of codimension 2n to generalized self-duality equations as Bogomol'nyi equations, by using a part of the spin connection.
