DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PIMS_GAP/8/"
 >Obstructing isotopy with an extra dimension</a>\nby Maggie Miller (Stanfo
 rd University) as part of PIMS Geometry / Algebra / Physics (GAP) Seminar\
 n\nLecture held in THORV 124.\n\nAbstract\nIn 1982\, Livingston showed tha
 t several examples of Seifert surfaces that are not isotopic in the $3$-sp
 here become isotopic when pushed into the $4$-ball. This is consistent wit
 h a common intuition in topology: objects that are somehow similar should 
 become the same when stabilized. We recently constructed families exhibiti
 ng that this is not always the case — that is\, surfaces in the $3$-sphe
 re that remain non-isotopic even when pushed into the $4$-ball. This is jo
 int work with Kyle Hayden\, Seungwon Kim\, JungHwan Park\, and Isaac Sundb
 erg.\n\nHybrid delivery (in person on University of Saskatchewan campus an
 d via Zoom).\n
