Aug 29, 2016 at 7:47 | comment | added | Thomas Rot | Let $\mathcal{K}_k^l$ be the space of index $k$ Fredholm operators whose kernel is $l$ dimensional. There is a fiber sequence $GL(\mathbb{H})\rightarrow \mathcal{K}_k^l\rightarrow BU(l)\times BU(k-l)$ where the right map is mapping an operator to the kernel times the cokernel. It follows that $\mathcal{K}_k^l$ is homotopy equivalent to $BU(l)\times BU(k-l)$. I do not now what happens when one takes the union over $l\leq l_0$. | |
