Research

(Updated 03/2013)

Currently I’m more or less interested in:

  • Symplectic and Poisson geometry, Lie groupoids and algebroids
  • Dynamical systems and singular foliations
  • Mathematical methods in finance and economy
  • Complexity

Some of the things that I did:

  • Local linearization theorem for proper Lie groupoids
  • Semi-local decomposition theorem for nondegenerate singularities of integrable Hamiltonian systems
  • Intrinsic torus actions for dynamical systems (the “toric philossophy”, which implies things like action-angle variables, Poicaré-Dulac normalization, etc.)
  •  Linearization of higher-codimension singular foliations
  • Levi decomposition (in infinite-dimensional situations)
  • Monodromy formulas for integrable Hamiltonian systems
  • Entropy of geometric structures
  • Non-Hamiltonian integrable systems
  • etc.
