Abstract

Let Xn r,s denote the blow-up of Pn along r general lines and s general points. In this paper, we focus on l-very ample line bundles on Xn 0,s and investigate their Seshadri constants with some restrictions on s. Additionally, we compute the nef cone of X3 r,0 for r ≤ 6 and study the Seshadri constants of some ample line bundles on it. We also examine the Seshadri constants of some ample line bundles on X4 r,0 (r ≤ 7) and X5 r,0 (r ≤ 5).
