论文摘要

异国纺纱球场来自非平凡拓扑歧管上的不相等的旋转结构,$ m $。这会在狄拉克运营商中引起一个额外的术语,该术语由同居组$ h^1(m,\ m rathbb {z} _2)$定义,该$统治了CECH共同体学类。这种形式主义扩展了任何有限维度的流形,并具有任意签名指标。加热核系数的外来校正,将异国情调的算子与$ m $的几何不变式相关的光谱特性进行了衍生和审查。

Exotic spinor fields arise from inequivalent spin structures on non-trivial topological manifolds, $M$. This induces an additional term in the Dirac operator, defined by the cohomology group $H^1(M,\mathbb{Z}_2)$ that rules a Cech cohomology class. This formalism is extended for manifolds of any finite dimension, endowed with a metric of arbitrary signature. The exotic corrections to heat kernel coefficients, relating spectral properties of exotic Dirac operators to the geometric invariants of $M$, are derived and scrutinized.
