Knots, L-spaces, and SL_2(R) representations
Jacob Rasmussen, Cambridge
Date & time: Monday, 12 December 2022 at 2:00PM - 3:00PM
The L-space conjecture of Boyer-Gordon-Watson and Juhasz relates threevery different properties that a closed orientable 3-manifold might have: having left orderable fundamental group, having a co-oriented taut foliation, and having a nonzero class in reduced Floer homology. I will discuss this conjecture and some things we can learn about it by thinking about representations of the fundamental group to SL_2(R).
