论文摘要
我们证明,规范扭曲$ζ\ colon K(\ Mathbb {z},3),\ rightArrow bgl_1(mspin^c)$不会扩展到统一的界限,通过表明每个连续的映射$ f \ colon k(\ mathbb {z},3),3)\ firoprow bgl_1(a firop firotar bgl_1 n o.
We prove that the canonical twist $ζ\colon K(\mathbb{Z},3) \rightarrow BGL_1(MSpin^c)$ does not extend to a twist for unitary bordism by showing that every continuous map $f \colon K(\mathbb{Z},3) \rightarrow BGL_1(MU)$ loops to a null homotopic map.
