Algebra/Topology Seminar
Algebra/Topology Seminar – Jonathan Simone (Georgia Institute of Technology)
ZoomTitle: The non-orientable 4-ball genus of torus knots Abstract: The non-orientable 4-ball genus of a knot $K$ in $S^3$ is the minimal first Betti number of any smoothly embedded non-orientable surface
Algebra/Topology Seminar – Surena Hozoori (Georgia Tech)
ZoomTitle: On Anosovity, divergence and bi-contact surgery Abstract: I will revisit the relation between Anosov 3-flows and invariant volume forms, from a contact geometric point of view. Consequently, I will
Algebra/Topology Seminar – Subhankar Dey (University of Alabama)
346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Detection results in link Floer homology Abstract: In this talk I will briefly describe link Floer homology toolbox and its usefulness. Then I will show how link Floer homology can
Algebra/Topology Seminar – Austin Christian (Georgia Tech)
ZoomTitle: Symplectic fillings of lens spaces Abstract: Many contact 3-manifolds arise as boundaries of symplectic 4-manifolds, and we are often interested in the filling problem for a given contact 3-manifold. That
Algebra/Topology Seminar – Alberto Cavallo (CIRGET/Renyi Institute)
ZoomTitle: Slice links and smooth 4-manifolds Abstract: We vary the trace embedding lemma in order to prove results about smooth, closed, simply connected 4-manifolds, studying smoothly slice links in them. We focus
Algebra/Topology Seminar – Orsola-Capovilla Searle (UC Davis)
ZoomTitle: Infinitely many Lagrangian Tori in Milnor fibers constructed via Lagrangian Fillings of Legendrian links Abstract: One approach to studying symplectic manifolds with contact boundary is to consider Lagrangian submanifolds with Legendrian
Algebra/Topology Seminar – Johnny Nicholson (Imperial College)
ZoomTitle: The homotopy type of a finite 2-complex with non-minimal Euler characteristic Abstract: Two presentations for a group G which have the same deficiency are called exotic if the corresponding presentation complexes
Algebra Topology Seminar – Tucker Ervin (UA)
346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Mutations of reflections and existence of pseudo-acyclic orderings for type An Abstract: In a recent paper by K.-H. Lee, K. Lee and M. Mills, a mutation of reflections in the
Algebra/Topology Seminar – Fraser Binns (Boston College)
346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Some Link Detection ResultsAbstract: A central question in low dimensional topology is; how can we distinguish links? In this talk I will discuss various classical invariants which can help
Symplectic topology of Brieskorn singularities – Cagri Karakurt (Bogazici University)
ZoomAbstract: Cagri will talk about some symplectic/contact topological aspects of Brieskorn singularities $x^p+y^q+z^r=0$. He’ll tell how to draw the surgery diagrams of their canonical contact structures and prove that the
