Title: Creating small Seifert fibered spaces by Dehn surgery on knots
Generically, a small Seifert fibered spaces may be viewed as a thrice-punctured sphere cross S^1 with a solid torus attached along each boundary torus. Sometimes an embedded solid torus may be excised from S^3 and then reattached along the resulting boundary torus in a different manner to produce one of these small Seifert fibered spaces; i.e. Dehn surgery on a knot in S^3 sometimes produces a small Seifert fibered space. The classification of such knots and Dehn surgeries remains open. We'll talk about the context for this problem, what's known, and some of our current on-going joint research with Cameron Gordon and John Luecke.
