Abstract:

We give a direct proof that the Freed–Lott differential analytic index is well defined and a condensed proof of the differential Grothendieck–Riemann–Roch theorem. As a byproduct we also obtain a direct proof that the $\mathbb {R}/\mathbb {Z}$ analytic index is well defined and a condensed proof of the $\mathbb {R}/\mathbb {Z}$ Grothendieck–Riemann–Roch theorem.
