   Format: MarkdownItexDominic Joyce had been announcing in his article linked to at [[smooth algebra]] an application of smooth locuses and a simple version of derived smooth manifolds to moduli spaces of curves. It seems that the announced work is not out yet, but somebody kindly informed me that there are <a href="http://people.maths.ox.ac.uk/joyce/dmtalk.pdf">these talk notes</a> with a little bit of further info. I wasn't sure where to archive tis. Ended up putting this into [[derived smooth manifold]],

   Format: MarkdownItexThere's a second version of [Algebraic Geometry over C-infinity rings](http://arxiv.org/abs/1001.0023) on the ArXiv now, coinciding with the appearance of a [survey](http://arxiv.org/abs/1104.4951) of the paper. A draft of a part of his book - "D-manifolds and d-orbifolds: a theory of derived differential geometry" - is available [here](http://people.maths.ox.ac.uk/joyce/dmanifolds.html).

   Format: MarkdownItexJoyce has a humorous [account](http://people.maths.ox.ac.uk/joyce/resint.html) of his research interests. And from a recent [talk](http://people.maths.ox.ac.uk/joyce/camtalk.pdf): >Derived manifolds were defined by David Spivak (Duke Math. J. 153, 2010), a student of Jacob Lurie. A lot of my ideas are stolen from Spivak. D-manifolds are much simpler than derived manifolds. D-manifolds are a 2-category, using Hartshorne- level algebraic geometry. Derived manifolds are an $\infty$-category, and use very advanced and scary technology -- homotopy sheaves, Bousfeld localization,... >D-manifolds are a 2-category truncation of derived manifolds. I claim that this truncation remembers all the geometric information of importance to symplectic geometers, and other real people.

   D-manifolds are a 2-category truncation of derived manifolds. I claim that this truncation remembers all the geometric information of importance to symplectic geometers, and other real people.
