Query: Cyclic branched covers of knots as links of real isolated singularities   Given a real analytic function $f$ from $\mathbb{R}^4$ to $\mathbb{R}^2$ with
isolated critical point at the origin, the link $L_f$ of the singularity is a
real fibred knot in $\mathbb{S}^{3}$. From this singularities, we construct a
family of real isolated suspension singularities from $\mathbb{R}^6$ to
$\mathbb{R}^2$ such that its links are the total spaces of the $n$-branched
cyclic coverings over the corresponding knots. In this way we obtain as links
of singularities, $3$-manifolds that does not appear in the complex case, such
as hyperbolic $3$-manifolds or the Hantzsche-Wendt manifold.
