摘要翻译:
设X是维数n的射影簇,L是X上的nef因子,用e_d(r;X,L)表示X中r个极一般点的D维Seshadri常数。我们证明了e_d(Rs;X,L)>=e_d(r;X,L)e_d(S;P^n,O_{P^n}(1))。

英文摘要:
Let X be a projective variety of dimension n and L be a nef divisor on X. Denote by e_d(r;X,L) the d-dimensional Seshadri constant of r very general points in X. We prove that e_d(rs;X,L) >= e_d(r;X,L)e_d(s;P^n,O_{P^n}(1)).
