On induced cycles of Levi graphs associated to line arrangements

Rupam Karmakar, Rajib Sarkar

In this article, we investigate the existence of induced cycles in Levi graphs associated to line arrangements in $P_{C}^{2}$ . We also look at the problem of findin…

Algebraic properties of binomial edge ideals of Levi graphs associated with curve arrangements

Rupam Karmakar, Rajib Sarkar, Aditya Subramaniam

In this article, we study algebraic properties of binomial edge ideals of Levi graphs associated with certain plane curve arrangements. Using combinatorial properties of Levi graph…

Seshadri constants on some blow-ups of projective spaces

Rupam Karmakar, Praveen Kumar Roy

Let $X_{r, s}^{n}$ denote the blow-up of $P^{n}$ along $r$ general lines and $s$ general points. In this paper, we focus on $l$ -very ample line bundles on $X_{0, s}^{n}$ and inves…

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}…
