Title: Dehn surgery on knots yielding lens spaces
Abstract: The latter half is on a recent joint work with
Hiroshi Goda.
There are many studies on the problem of what
kind of a knot admits Dehn surgery yielding a lens space,
or the problem of what lens space can be obtained
by Dehn surgery on knots.
We will focus on the genera of knots, and we give an estimate
of the order of the fundamental group of a lens space
obtained by Dehn surgery on a knot,
by using the labeled graphs on a Seifert surface
and a Heegaard torus of a lens space.
In particular, we will prove that a genus one knot K
admits Dehn surgery yielding a lens space if and only if
K is the trefoil.
