SUMMARY: (...): Joackim BERNIER - Exact splitting methods for semigroups ge
 nerated by inhomogeneous quadratic differential operators
DESCRIPTION:: Joackim BERNIER (Institut de Mathématiques de Toulouse)\n\nI
  will present some general tools to factorize semigroups generated by inho
 mogeneous quadratic differential operators as product of more elementary s
 emigroups. On the one hand\, I will explain how such a factorization can b
 e used to characterize geometrically the regularizing effects of these sem
 igroups. On the other hand\, from a numerical point of view\, we will see 
 how it can be used to get some efficient and accurate splitting methods. I
  will highlight the efficiency of these new methods on the examples of the
  magnetic Schrödinger equations with harmonic potentials and some Fokker-
 Planck equations. This talk will rely on some joint works with Paul Alphon
 se\, Nicolas Crouseilles\, Fernando Casas and Yingzhe Li.
