# nLab D-geometry

This entry is about the concept in the algebraic geometry of jet bundles and differential equations. For the concept of geometry as seen by D-branes see at D-brane geometry.

## Idea

The term $\mathcal{D}$-geometry refers to a synthetic formulation of differential geometry with a focus on the geometry of de Rham spaces. A quasicoherent sheaf of modules over a de Rham space is called a D-module, short for module over the algebra of differential operators, which is where the term “D-geometry” derives from.
