Effective cones of cycles on products of projective bundles over curves

Rupam Karmakar

Let $X = P (E_{1}) \times_{C} P (E_{2})$ where $C$ is a smooth curve and $E_{1}$ , $E_{2}$ are vector bundles over $C$ .In this paper we compute the pseudo effective cones of h…

Nef cone and Seshadri constants on products of projective bundles over curves

Rupam Karmakar, Snehajit Misra

Let $X = P (E_{1}) \times_{C} P (E_{2})$ where $C$ is a smooth curve and let $E_{1}$ , $E_{2}$ be vector bundles over $C$ . In this paper, we extend the results in \cite{K-M-R}…
