题  目：Linear Independence in the Concordance Group and Knot Floer Invariants

时  间：2021.12.01（星期三），14:30-16:30

地  点：南楼N802室

摘  要：The first half of this talk is expository, introducing the knot concordance group and Heegaard knot Floer theory. We will survey a few invariants arising from the knot Floer complex. Then some families of knots will be given as examples to show how the invariants are used to prove linear independence. Finally, we will discuss concordance problems about algebraic knots.
