Differentiating $L_{\infty}$ groupoids

Du Li, Leonid Ryvkin, Arne Wessel +1

Differentiating an Lie $n$ -groupoid via the differential-geometric fat point a priori only yielads a presheaf of graded manifolds. In this article we prove that this presheaf is re…

A singular Serre-Swan theorem via tepui fibrations

Alfonso Garmendia, David Miyamoto, Leonid Ryvkin

The classical Serre-Swan theorem asserts that any finitely generated projective module over the algebra $C^{\infty} (M)$ of smooth functions of a manifold $M$ can be realized as the s…

Universal central extension of the Lie algebra of exact divergence-free vector fields

Bas Janssens, Leonid Ryvkin, Cornelia Vizman

We construct the universal central extension of the Lie algebra of exact divergence-free vector fields, proving a conjecture by Claude Roger from 1995. The proof relies on the anal…
