On the existence of curves in n with stable normal bundle

Edoardo Ballico, Luciana Ramella (1999)

Annales Polonici Mathematici

Similarity:

We prove that for integers n,d,g such that n ≥ 4, g ≥ 2n and d ≥ 2g + 3n + 1, the general (smooth) curve C in n with degree d and genus g has a stable normal bundle N C .

On jets of surfaces.

Fernando Etayo Gordejuela (1991)

Collectanea Mathematica

Similarity:

We study the 2-jet bundle of mappings of the real plane into a manifold. We shall prove that there exists an imbedding of this 2-jet bundle into a suitable first order jet bundle, in such a way that its image is the set of fixed points of a canonical automorphism of the biggest jet bundle.

Strata of smooth space curves having unstable normal bundle

Luciana Ramella (1999)

Bollettino dell'Unione Matematica Italiana

Similarity:

Per d g , vengono trovate curve liscie in P 3 di grado d e genere g aventi fibrato normale instabile con grado di instabilità σ , per ogni 1 σ d - 4 . Inoltre per 4 g - 2 σ d - 4 , viene trovata una famiglia di curve in P 3 di grado d e genere g avente fibrato normale instabile con grado di instabilità σ e formante uno strato dello schema di Hilbert della giusta dimensione che è 4 d - g + 1 - 2 σ .
