Why does the index of the Dirac operator on a manifold with boundary live inside the Pfaffia...
I am trying to understand a statement from page 72 of What is an elliptic object? by Stolz and Teichner.
They have a spin Riemannian 2-manifold $\Sigma$, with boundary 1-manifold $Y$. The Dirac oper …

Homotopy Fixed Points of SO(2) on Fully Dualizable Algebras
Note: by fixed points, I always mean homotopy fixed points.
As explained in Jacob Lurie's paper on the cobordism hypothesis, we have an action of O(2) on the $\infty $-groupoid $X$ given by consideri …
