The flat Grothendieck–Riemann–Roch theorem without adiabatic techniques
© 2016 Elsevier B.V. In this paper we give a simplified proof of the flat Grothendieck–Riemann–Roch theorem. The proof makes use of the local family index theorem and basic computations of the Chern–Simons form. In particular, it does not involve any adiabatic limit computation of the reduced eta-invariant.
