The nerve of a differential graded algebra

Friday 5th April 2013 - 09:30 to 10:30
INI Seminar Room 1
The nerve of a differential graded algebra is a quasicategory: in this talk, we explain what the quasi-iso-morphisms look like in this quasicategory. If the dg algebra A is a dg Banach algebra concentrated in dimensions i>-n , the nerve of A is a Lie n-stack, that is, a quasicategory enriched in Banach analytic spaces. We show that Kuranishi's approach yields a finite dimensional Lie n-stack parametrizing deformations of a complex of holomorphic vector bundles on a compact complex manifold of length n. This is joint work with Kai Behrend.
