Hello everyone,

Brandy Doleshal will be speaking in seminar today. Her title and abstract are below. We are going to Cafe 88 for lunch now, if anyone is interested. Seminar is at 3:30 and we will be going out to dinner at 5:30 at Hideaway. Everyone is welcome. Also, we will probably be going out tomorrow for lunch as well. Email me if you are interested in that.

Title: Surgery equivalent primitive/Seifert knots

Abstract:

The primitive/primitive and primitive/Seifert knots are families of knots on the genus 2 surface with the property that surgery at the surface slopes yields lens space and Seifert fibered space surgeries. We call two knots from this class surgery equivalent if they have the same surgery at the surface slope. In this talk, we will discuss what is known about surgery equivalent primitive/Seifert knots. This is joint work with Jeffrey Meier.
