Varieties with one apparent double point

C. Ciliberto, M. Mella, F. Russo

The number of apparent double points of a smooth, irreducible projective variety $X$ of dimension $n$ in $\Proj^{2n+1}$ is the number of secant lines to $X$ passing through the gen…

Pillow Degenerations of K3 Surfaces

Ciro Ciliberto, Rick Miranda, Mina Teicher

In this article we construct a specific projective degeneration of K3 surfaces of degree 2g-2 in P^g to a union of 2g-2 planes, which meet in such a way that the combinatorics of t…

On surfaces with $p_{g} = 2$ , $q = 1$ and non-birational bicanonical map

Ciro Ciliberto, Margarida Mendes Lopes

In the present note we show that any surface of general type with $p_{g} = 2$ , $q = 1$ and non-birational bicanonical map has a pencil of curves of genus 2. Combining this result with pre…
