Abstract: We prove a Kastler‐Kalau‐Walze type theorem for perturbations of Dirac operators on compact manifolds with or without boundary. As a corollary, we give two kinds of operator‐theoretic explanations of the gravitational action on boundary. We also compute the spectral action for Dirac operators with two‐form perturbations on 4‐dimensional compact manifolds.
