Cobordism, spin structures, and profinite completions

Sam Hughes, Andrew Ng

Let $M$ and $N$ be smooth closed connected aspherical manifolds with good (in the sense of Serre) fundamental groups $G$ and $H$ . We show that if $G ≅ H$ , then…

Simple groups and complements of smooth surfaces in simply connected $4$ -manifolds

Sam Hughes, Daniel Ruberman

For each integer $n$ we construct an oriented closed simply connected $4$ -manifold $X$ admitting a smoothly embedded closed connected surface $Σ$ of self-intersection number $n$ su…
