DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GOSS2021/3/"
 >Heegaard Splittings and Trisections 101: A Crash Course in Manifold Decom
 positions in Dimensions Three and Four</a>\nby Nick Meyer (University of N
 ebraska\, Lincoln) as part of Graduate Online Seminar Series (GOSS)\n\nLec
 ture held in TBA.\n\nAbstract\nIn this talk\, I will discuss Heegaard spli
 ttings of 3-manifolds and trisections of 4-manifolds. These decompositions
  cut the manifold into 1-handlebodies of appropriate dimension whose commo
 n intersection is a closed\, orientable surface. By studying these decompo
 sitions\, we obtain lots of information about the manifolds that they dete
 rmine. This talk is based in part on David Gay's "From Heegaard splittings
  to trisections\; porting 3-dimensional ideas to dimension 4."\n
