报告内容摘要： Let K be a tunnel number one knot in M, where M is either S3, S2×S1, or a connected sum of S2×S1with a lens space. We prove that if a Dehn surgery on K yields a lens space, then K is a doubly primitive knot in M. For M =S3, this resolves the tunnel number one Berge Conjecture. For M =S2×S1, this resolves a conjecture of Greene and Baker-Buck-Lecuona for tunnel number one knots. This is joint work with Yoav Moriah and Tali Pinsky.
