제목: Knots in the 3-sphere admitting Seifert Dehn surgeries.
초록: Dehn surgery on a knot in the 3-sphere is one way of constucting a new manifold from the 3-sphere, i.e. the manifold obtained from the 3-sphere with a regular neighborhood of a knot removed by gluing a solid torus back in a different way. In this talk, I will give the overview
on knots in the 3-sphere admitting a Dehn surgery of Seifert-fibered space. Several classes of knots are known to have Seifert-fibered space Dehn surgeries; the unknot, Torus knots, Berge knots, Dean knots and so on. I will talk the last two classes more specifically and give more examples of such knots.
