Geometry and Topology

Renaud Detcherry, Bourgogne, will be speaking.

The presentation titl is "A quantum obstruction to purely cosmetic surgeries."

Contact Honghao Gao (gaohongh@msu.edu) for more information.

The cosmetic surgery conjecture asks whether it is possible that two Dehn-surgeries on the same non-trivial knot in S³ give the same oriented 3-manifolds. We will present new obstructions for a knot to admit purely cosmetic surgeries, using Reshetikhin-Turaev invariants.
