Hello everyone,

Today Henry will be speaking at 2:30 in room 405. His title and abstract are here:

Title: Dehn surgery by shearing Abstract: I’ll talk about a new (to me) way to think about Dehn surgery. We implement (p,q) Dehn surgery within a solid torus by slicing along an annulus from the boundary to the core curve, then regluing with a varying amount of shear around the annulus.
