Abstract

Let kk be a field of characteristic 0 and A\mathcal{A} a curved kk-algebra. We obtain a Chern-Weil-type formula for the Chern character of a perfect A\mathcal{A}-module taking values in HN0II(A)HN_0^{II}(\mathcal{A}), the negative cyclic homology of the second kind associated to A\mathcal{A}, when A\mathcal{A} satisfies a certain smoothness condition.
