Very ample line bundles on weighted projective spaces and weighted blowups

Stevell Muller, Erik Paemurru

We consider line bundles $O (k d)$ on weighted projective spaces, where $k$ is an integer and $d$ is the least common multiple of the weights. Such line bundles are ample i…

Local inequalities for $c A_{k}$ singularities

Igor Krylov, Takuzo Okada, Erik Paemurru

We generalize an intersection-theoretic local inequality of Fulton-Lazarsfeld to weighted blowups. As a consequence, we obtain the $4 n^{2} / (k + 1)$ -inequality for isolated $c A_{k}$ singu…

Blowups of smooth hypersurfaces, their birational geometry and divisorial stability

Livia Campo, Tiago Duarte Guerreiro, Erik Paemurru

Let $X$ be a smooth $n$ -dimensional Fano hypersurface in $P^{n + 1}$ where $n \geq 3$ . Let $Γ$ be a smooth positive-dimensional complete intersection of $X$ , a hypersurface a…
