AMS Special Session on Heegaard Splittings of 3-manifolds and Trisections of 4-manifolds

• Thursday January 9, 2025, 8:00 a.m.-12:00 p.m.
  AMS Special Session on Heegaard Splittings of 3-manifolds and Trisections of 4-manifolds, I
  Topologists often study abstract spaces by cutting them into simple pieces. Every 3-dimensional manifold can be broken into two handlebodies in a decomposition known as a Heegaard splitting, whereas in dimension four, every space can be cut into three such pieces. This special session will bring together researchers studying these two related decompositions, and participants will explore the interplay of tools and techniques between dimensions three and four.
