BV-generators and Lie algebroids

Sebastien Michea, Gleb Novitchkov

Let $A = A^{0} + A^{1} + A^{2} + ...$ be a Gerstenhaber algebra generated by $A^{0}$ and $A^{1}$ . Given a degree -1 operator $D$ on $A^{0} + A^{1}$ , we find the condition on $D$ that makes $A$ a BV-alge…

Tire track geometry: variations on a theme

Serge Tabachnikov

We study closed smooth convex plane curves $Γ$ enjoying the following property: a pair of points $x, y$ can traverse $Γ$ so that the distances between $x$ and $y$ along the curve an…

Chern-Weil map for principal bundles over groupoids

Camille Laurent-Gengoux, Jean-Louis Tu, Ping Xu

The theory of principal $G$ -bundles over a Lie groupoid is an important one, unifying the various types of principal $G$ -bundles, including those over manifolds, those over orbifol…
