An infrasolvmanifold which does not bound

J. A. Hillman

Every 4-dimensional infrasolvmanifold $M$ with $β_{1} (M; Q) > 0$ or which is flat or has one of the geometries $N i l^{4}$ , $S o l_{m, n}^{4}$ , or $S o l_{0}^{4}$ b…

Parallelizability of 4-dimensional infrasolvmanifolds

J. A. Hillman

We show that if $M$ is an orientable 4-dimensional infrasolvmanifold and either $β = β_{1} (M; Q) \geq 2$ or $M$ is a $S o l_{0}^{4}$ - or a $S o l_{m, n}^{4}$ -manifold (wit…
