DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BOWL/23/">Fo
 liations of 3-manifolds of positive scalar curvature by surfaces of contro
 lled size</a>\nby Yevgeny Liokumovich (Toronto) as part of B.O.W.L Geometr
 y Seminar\n\n\nAbstract\nLet M be a compact 3-manifold with scalar curvatu
 re at least 1. We show that there exists a Morse function f on M\, such th
 at every connected component of every fiber of f has genus\, area and diam
 eter bounded by a universal constant. The proof uses Min-Max theory and Me
 an Curvature Flow. This is a joint work with Davi Maximo. Time permitting\
 , I will discuss a related problem for macroscopic scalar curvature in met
 ric spaces (joint with Boris Lishak\, Alexander Nabutovsky and Regina Rotm
 an).\n
