Title: On Dehn surgeries between S1xS2 and lens spaces
Abstract: We consider knots in S1 x S2 with a Dehn surgery to a lens space
and how this parallels what happens for knots in S3. The Cyclic Surgery
Theorem enables a classification for non-longitudinal surgeries, while
Berge's families of doubly primitive knots in S3 motivate our
conjectural classification for longitudinal surgeries. We will compare this
conjectural picture with the Berge Conjecture pointing out their
differences and similarities.
