Engel structures on complex surfaces

Nicola Pia, Giovanni Placini

We classify complex surfaces $(M, J)$ admitting Engel structures $D$ which are complex line bundles. Namely we prove that this happens if and only if $(M, J)$ has trivi…

On the dynamics of some vector fields tangent to non-integrable plane fields

Nicola Pia

Let $E^{3} \subset T M^{n}$ be a smooth $3$ -distribution on a smooth manifold of dimension $n$ and $W \subset E$ a line field such that $[\mathcal{W},\mathcal…

Riemannian properties of Engel structures

Nicola Pia

This paper is about geometric and Riemannian properties of Engel structures, i.e. maximally non-integrable $2$ -plane fields on $4$ -manifolds. Two $1$ -forms $α$ and $β$ are called E…
