Free Actions of Extraspecial $p$ -Groups on $S^{n} \times S^{n}$

Ian Hambleton, Ozgun Unlu

Let $p$ be an odd regular prime, and let $G_{p}$ denote the extraspecial $p$ --group of order $p^{3}$ and exponent $p$ . We show that $G_{p}$ acts freely and smoothly on $S^{2p-1} \times…

Non-smoothable four-manifolds with cyclic fundamental group

Stefan Friedl, Ian Hambleton, Paul Melvin +1

In [HT], two of us constructed a closed oriented 4-dimensional manifold with fundamental group $Z$ that does not split off $S^{1} \times S^{3}$ . In this note we show that this 4-manifo…
