A d-shifted Darboux theorem

Abstract

We give a local model for d-shifted symplectic dg-schemes, or Deligne-Mumford dg-stacks [PTVV]. Locally any such is a product of a "twisted shifted cotangent bundle", where the twist is given by an element df, with fH1d(\CalO)f \in H^{1-d}(\Cal O), and a quadratic bundle in middle degree. The latter only occurs if d = 4r+2.
