Bigraded cochain complexes and Poisson cohomology
Andrés Pedroza, Eduardo Velasco-Barreras, Yury Vorobiev
We present an algebraic framework for the computation of low-degree cohomology of a class of bigraded complexes which arise in Poisson geometry around (pre)symplectic leaves. We al…

On the Global Structure of Normal Forms for Slow-Fast Hamiltonian Systems
M. Avendaño Camacho Yu. Vorobiev
In the framework of Lie transform and the global method of averaging, the normal forms of a multidimensional slow-fast Hamiltonian system are studied in the case when the flow of t…
