Poisson Cohomology of Broken Lefschetz Fibrations
Panagiotis Batakidis, Ramón Vera
We compute the formal Poisson cohomology of a broken Lefschetz fibration by calculating it at fold and Lefschetz singularities. Near a fold singularity the computation reduces to t…

Biquantization techniques for computing characters of differential operators on Lie groups
Panagiotis Batakidis
We sketch the proof that the biquantization character of Cattaneo-Torossian equals a standard character computed in harmonic analysis. An old example is treated this way to produce…

Deformation quantization and invariant differential operators
Panagiotis Batakidis
The isomorphism between the reduction algebra and the invariant differential operators on G/H is sketched.
