Sekundarni naslov: | Kompletne nesingularne holomorfne foliacije na Steinovih mnogoterostih |
Sekundarni povzetek: | Let ▫$X$▫ be a Stein manifold of complex dimension ▫$n \ge 1$▫ endowed with a Riemannian metric ▫${\mathfrak g}$▫. We show that for every integer ▫$k$▫ with ▫$\left[\frac{n}{2}\right] \le k \le n-1$▫ there is a nonsingular holomorphic foliation of dimension ▫$k$▫ on ▫$X$▫ all of whose leaves are topologically closed and ▫${\mathfrak g}$▫-complete. The same is true if ▫$1\le k \left[\frac{n}{2}\right]$▫ provided that there is a complex vector bundle epimorphism ▫$TX\to X \times \mathbb{C}^{n-k}$▫. We also show that if ▫$\mathcal{F}$▫ is a proper holomorphic foliation on ▫$\mathbb{C}^n$▫ ▫$(n > 1)$▫ then for any Riemannian metric ▫${\mathfrak g}$▫ on ▫$\mathbb{C}^n$▫ there is a holomorphic automorphism ▫$\Phi$▫ of ▫$\mathbb{C}^n$▫ such that the image foliation ▫$\Phi_*\mathcal{F}$▫ is ▫${\mathfrak g}$▫-complete. The analogous result is obtained on every Stein manifold with Varolin's density property. |
