Joint Seminar: Eylem Yıldız (Michigan State) "Knot Concordances in S^1 x S^2 and Constructing Akbulut-Ruberman Type Exotic 4-Manifolds"

Date and time:
Boyd Room 328

Knot Concordances in S^1 x S^2 and Constructing Akbulut-Ruberman Type Exotic 4-Manifolds

I will discuss knot concordances in 3-manifolds. In particular I will talk about knot concordances of knots in the free homotopy class of S^1 x {pt} in S^1 x S^2. It turns out, we can use some of these concordances to construct Akbulut-Ruberman type exotic 4-manifolds. As a consequence, at the end of the talk we will see absolutely exotic Stein pair of 4-manifolds. This is joint work with Selman Akbulut.
