トポロジーセミナー（2017/09/04）
topology
日時：2017年9月4日（月）16：10〜17：10
場所：筑波大学 自然系学系D棟D509
講演者：Min Hoon Kim 氏 （Korea Institute for Advanced Study）
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.
