The curvature of left-invariant magnetic systems
Shane Rankin, Ivo Terek, David Weed
We compute the magnetic curvatures (in the sense of Assenza) of left-invariant magnetic systems on Lie groups and explore relations between curvature properties and algebraic prope…

Algebroid Desingularizable Poisson Structures
Shane Rankin
We introduce algebroid desingularizable Poisson manifolds, a class of Poisson manifolds induced by symplectic Lie algebroids with almost-injective anchors, generalizing structures…

The Hard Lefschetz Theorem on Kähler Lie Algebroids
Shane Rankin
Compact Kähler manifolds classically satisfy the Hard Lefschetz Theorem, which gives strong control on the underlying topology of the manifold. One expects a similar theorem to be…
