• We show that every sheaf on the site of smooth manifolds with values in a stable $$(\infty ,1)$$(∞,1)-category (like spectra or chain complexes) gives rise to a “differential cohomology diagram” and a homotopy formula, which are common features of all classical examples of differential cohomology theories. These structures are naturally derived from a canonical decomposition of a sheaf into a homotopy invariant part and a piece which has a trivial evaluation on a point. In the classical… CONTINUE READING
