DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/38/">Eu
 ler class of taut foliations on Q-homology spheres and Dehn fillings</a>\n
 by Ying Hu (UNO) as part of Geometry and topology online\n\n\nAbstract\n<p
 >\n        The Euler class of an oriented plane field\n        over a thre
 e-manifold is a second cohomology class\, which\n        determines the pl
 ane field up to isomorphism.  In this talk\,\n        we will discuss the 
 Euler class of taut foliations on a\n        \\(\\QQ\\)-homology sphere. W
 e view \\(\\QQ\\)-homology spheres as\n        Dehn fillings on knot manif
 olds and give necessary and\n        sufficient conditions for the Euler c
 lass of taut foliations\n        on such manifolds to vanish. We will also
  apply these results\n        to study the orderability of three-manifold 
 groups.\n      </p>\n
