Title:  Godbillon-Vey classes of Lie subalgebroids

Absrtact:  The Godbillon-Vey class is a secondary characteristic class 
defined for regular foliations and has been studied extensively. On the 
other hand, extending the Godbillon-Vey class to the setting of singular 
foliations is a difficult problem. A Lie algebroid is a generalization 
of the tangent bundle and is known to induce a singular foliation. In 
this talk, we define relative Godbillon-Vey classes for Lie 
subalgebroids and study their properties. We also present several 
concrete examples.
