Morse 2-functions and trisections of 4-manifolds
If you have a question about this talk, please contact Ivan Smith.
In joint work with David Gay, we show existence and uniqueness of Morse 2-functions (also known as broken Lefschetz fibrations), and then existence and uniqueness (up to stabilization) of trisections of 4-manifolds (analogous to Heegaard splittings of 3-manifolds).
