SUMMARY:Nielsen realization problem for 3-manifolds
LOCATION:Hill 705
DESCRIPTION:<p>In this talk, I will describe a joint work with Bena Tshishiku on Nielse
 n Realization problem for 3-manifolds, in particular, about the twist subgr
 oup. The twist subgroup is a normal finite abelian subgroup of the mapping 
 class group of 3-manifold, generated by the sphere twist. The proof mainly 
 uses the geometric sphere theorem/torus theorem and geometrization.</p>
