Seshadri constants on blow-ups of Hirzebruch surfaces

Krishna Hanumanthu, Cyril J. Jacob, Suhas B. N. +1

Let $e, r \geq 0$ be integers and let $F_{e} := P (O_{P^{1}} \oplus O_{P^{1}} (- e))$ denote the Hirzebruch surface with invariant $e$ …

Seshadri constants of curve configurations on surfaces

Krishna Hanumanthu, Praveen Kumar Roy, Aditya Subramaniam

Let $X$ be a complex nonsingular projective surface and let $L$ be an ample line bundle on $X$ . We study multi-point Seshadri constants of $L$ at singular points of certain arrange…

Seshadri constants on some flag bundles

Krishna Hanumanthu, Jagadish Pine

Let $X$ be a smooth complex projective curve and let $E$ be a vector bundle on $X$ which is not semistable. We consider a flag bundle $π : Fl (E) \to X$ parametrizing certain…

Some results on Seshadri constants of vector bundles

Indranil Biswas, Krishna Hanumanthu, Snehajit Misra

We study Seshadri constants of certain ample vector bundles on projective varieties. Our main motivation is the following question: Under what conditions are the Seshadri constants…
