Title: TBA Abstract: TBA
  Title: ADE links and cyclic branched covers Abstract: The Dynkin diagrams of types A,D and E arise in many classification problems in mathematics. We conjecture a modest addition to this list: the fibered links that induce the standard tight contact structure on S3 and have some cyclic branched cover an L-space. We will discuss progress towards a proof of this conjecture. This is joint work with Michel Boileau and Steve Boyer.
Title : Cyclic branched covers and the L-space conjecture Abstract : We survey what is known about the L-space conjecture for manifolds obtained as cyclic branched covers of links in the 3-sphere and report, in particular, on joint work with Michel Boileau and Cameron Gordon and with Ying Hu.
Title: Euler class and taut foliations on surgered 3-manifolds Abstract. This talk is motivated by the conjecture: the fundamental group of a QHS is left-orderable if and only if it admits a co-orientable taut foliation. It is known that if the Euler class of the taut foliation vanishes, then the fundamental group is left-orderable. In this talk, we will investigate the Euler class of co-orientable taut foliations on 3- manifolds which are…
Title: Distortion and the Bridge Distance of Knots Abstract: Distortion is a measure of the complexity of a knot that was first defined by Gromov. Pardon showed that the distortion of a knot is bounded below by a constant multiple of the representativity of the knot. We extend his techniques to show that there is a lower bound on the distortion of a knot proportional to the minimum of the bridge distance and the bridge number of the knot. We…
Title: Homology directions and veering triangulations Abstract: The cone over a fibered face of a hyperbolic 3-manifold has a nice characterization as the dual of the so-called cone of homology directions of a certain pseudo-Anosov flow. We give a new characterization of this cone of homology directions in terms of Agols veering triangulations.
Title: Invariants of tangles from the Fukaya category of the 4-punctured sphere Abstract: I will discuss a reinterpretation of Bar-Natans description of Khovanov homology in terms of immersed curves in the 4-punctured sphere. This point of view has some interesting algebraic consequences; the talk will focus on examples. This is joint work with Artem Kotelskiy and Claudius Zibrowius.
Title: Taut foliations and Seiberg-Witten invariants Abstract: The question of existence and flexibility of taut foliations on a three-manifold has been studied for decades. Kronheimer, Mrowka, Ozsvath, and Szabo obtained Floer-theoretic obstructions for the existence of taut foliations on rational homology spheres by considering its perturbation to contact structures. By showing that the perturbed contact structure is unique in many cases,…
