Blowups of Dirac structures
Ioan Marcut, Andreas Schüßler, Marco Zambon
Given a real, twisted Dirac structure on a smooth manifold , and a closed embedded submanifold of codimension , we characterise when lifts to a smooth…

The blow-down map in Lie algebroid cohomology
Andreas Schüßler
We study the blow-down map in cohomology in the context of real projective blowups of Lie algebroids. Using the blow-down map in cohomology we compute the Lie algebroid cohomology…

The Serre spectral sequence of a Lie subalgebroid
Ioan Mărcuţ, Andreas Schüßler
We study a spectral sequence approximating Lie algebroid cohomology associated to a Lie subalgebroid. This is a simultaneous generalisation of several classical constructions in di…
