abstract

In this paper, we prove that any closed orientable 3-manifold $M$ other than $\#^k S^1\times S^2$ and $S^3$ satisfies the following properties: (1) For any compact orientable 4-manifold $N$ bounded by $M$, the inclusion does not induce an isomorphism on their fundamental groups $\pi_1$. (2) For any map $f:M\to N$ from $M$ to a closed orientable 4-manifold $N$, $f$ does not induce an isomorphism on $\pi_1$. Relevant results on higher dimensional manifolds are also obtained.

  1. $\pi_1$-injective bounding and application to 3- and 4-manifolds

    math.GT 2025-06 conditional novelty 7.0 of 10

    A closed oriented manifold that bounds can be made to bound a manifold whose fundamental group is residually finite or finite, matching its own fundamental group, with applications to 3- and 4-manifolds.
