非对易环面上Yang-Mills两种方法的等价性
Equivalence of Two Approaches to Yang-Mills on Non-commutative Torus
摘要:
在非交换几何中有两种杨-米尔斯作用泛函的概念。我们证明,对于非交换n-环面,这两个概念都一致。我们还证明了$C^*$-代数的谱不变子代数上的非线性生成投射模的Hermite结构的一个结构定理。
英文摘要:
There are two notions of Yang-Mills action functional in noncommutative geometry. We show that for noncommutative n-torus both these notions agree. We also prove a structure theorem on the Hermitian structure of a finitely generated projective modules over spectrally invariant subalgebras of $C^*$-algebras.
