Algebra/Topology Seminar
Algebra/Topology Seminar – JungHwan Park (Georgia Institute of Technology)
ZoomTitle: On rationally slice knots Abstract: A knot in the three-sphere is called slice if it bounds a smooth disk in the four-ball. If one only requires the disk to be
Algebra/Topology Seminar – Marco Trombetti (University of Naples Federico II)
ZoomTitle: Abstract Infinite Group Theory in Linear Groups. Abstract: It is a classical result that the commutator subgroup of a group $G$ is finite whenever such is the factor group
Algebra/Topology Seminar – Ina Petkova (Dartmouth College)
ZoomTitle: A contact invariant from bordered Heegaard Floer homology Abstract: Given a contact structure on a bordered 3-manifold, we describe an invariant which takes values in the bordered sutured Floer

ZoomTitle: A combinatorial description of the knot concordance invariant epsilon Abstract: Sitting at the intersection of 4-dimensional topology and knot theory, the knot concordance group is an important object in
Algebra/Topology Seminar – Eamonn Tweedy (Widener University)
ZoomTitle: The co-rank of three-dimensional homology handlebody groups Abstract: A group G is called very large if G has a non-abelian free quotient. We examine the question of which three-manifolds

ZoomTitle: The second term in knot Floer homology Abstract: It is well known that the genus g of a knot is the highest Alexander grading for which the knot Floer homology is

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Fixed Q under the reverse operation in the RSK correspondence Abstract: The RSK correspondence is a bijection between permutations and pairs of standard Young tableaux with identical shape, where the tableaux
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
