| Abstrakt: | 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 investigate their Seshadri constants with some restrictions on s. Additionally, we compute the nef cone of X r , 0 3 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 X r , 0 4 (r ≤ 7) and X r , 0 5 (r ≤ 5). [ABSTRACT FROM AUTHOR] |
