Powers of ample divisors and syzygies of projective varieties

Huy Tai Ha

摘要:

设X是一个不需要光滑的射影簇,L是X上的一个充分因子。本文证明了存在整数c和b使得对任意非负整数p,L^d是正规生成的,并且嵌入X作为一个簇,该簇定义的理想具有直到第p步的线性合轨(即L^d具有性质N_p),对所有d >= cp + b.

英文摘要:

Suppose X is a projective variety, which needs not be smooth, and L an ample divisor on X. We show that there are integers c and b such that for any nonnegative integer p, L^d is normally generated and embeds X as a variety who defining ideal has linear syzygies upto the p-th step (i.e. L^d has property N_p) for all d >= cp + b.
