Cartan calculus for $C^\infty$-ringed spaces

Differential Geometry 2025-09-10 v3

Abstract

In an earlier paper (arXiv:2212.11163) I constructed a complex of differential forms on a local CC^\infty-ringed space. In this paper I define a sheaf of vector fields (``the tangent sheaf'') on a local CC^\infty-ringed space, define contractions of vector fields and forms, Lie derivatives of forms with respect to vector fields, and show that the standard equations of Cartan calculus hold for vector fields and differential forms on local CC^\infty-ringed spaces.
