DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSUGGT/30/">
 Homotopy motions of surfaces in 3-manifolds</a>\nby Makoto Sakuma (Hiroshi
 ma U) as part of Ohio State Topology and Geometric Group Theory Seminar\n\
 n\nAbstract\nWe introduce the concept of a homotopy motion of a subset in 
 a manifold\,  and give a systematic study of homotopy motions of surfaces 
 in closed orientable 3-manifolds. This notion arises from various natural 
 problems in 3-manifold theory such as domination of manifold pairs\, homot
 opical behaviour of simple loops on a Heegaard surface\, and monodromies o
 f virtual branched covering surface bundles associated to a Heegaard split
 ting. This is a joint work with Yuya Koda (arXiv:2011.05766).\n
