講演題目 Irreducible 3-manifolds that cannot be obtained by 0-surgery on a knot
アブストラクト We give infinitely many examples of closed, orientable, irreducible
3-manifolds $M$ such that $b_1(M)=1$ and $\pi_1(M)$ has weight 1,
but $M$ is not the result of Dehn surgery along a knot in the 3-sphere.
This answers a question of Aschenbrenner, Friedl and Wilton.
This is joint work with Matt Hedden and Kyungbae Park.
