On curves lying on a rational normal surface scroll

Wanseok Lee, Euisung Park

In this paper, we study the minimal free resolution of non-ACM divisors $X$ of a smooth rational normal surface scroll $S = S (a_{1}, a_{2}) \subset P^{r}$ . Our main result shows…

On surfaces of maximal sectional regularity

Markus Brodmann, Wanseok Lee, Euisung Park +1

We study projective surfaces $X \subset P^{r}$ (with $r \geq 5$ ) of maximal sectional regularity and degree $d > r$ , hence surfaces for which the Castelnuovo-Mumford regular…

Projective varieties of maximal sectional regularity

Markus Brodmann, Wanseok Lee, Euisung Park +1

We study projective varieties $X \subset P^{r}$ of dimension $n \geq 2$ , of codimension $c \geq 3$ and of degree $d \geq c + 3$ that are of maximal sectional regularity, i.e…
