On a special class of smooth codimension two subvarieties in $\mathbb{P}^n$, $n \geq 5$

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/69063We consider smooth codimension two subcanonical subvarieties in $\mathbb{P}^n$ with $n \geq 5$, lying on a hypersurface of degree $s$ having a linear subspace of multiplicity $(s-2)$. We prove that such varieties are complete intersections. We also give a little improvement to some earlier results on the non existence of rank two vector bundles on $\mathbb{P}^4$ with small Chern classes.10 pages.
