摘要
给出λn(x)=nk=1|z-xk|s|lk(x)|t和它的更广泛形式∧n(x)=jnk=in|x-xk|s|lk(x)|t的精确阶,它们分别是1ni-1和1mt-1n,其中s,t是满足s≥t≥1的固定实数,1≤in≤jn≤n,mn=jn-in+1。
In this paper we give the exact order of λ n(x)=n k=1 |x-x k| s|l k(x)| t and ∧ n(x)= j n k=i n |x-x k| s|l k(x)| t for any fixed real numbers s and t satisfied s≥t≥1, which are 1n t-1 and 1(j n-i n+1) t-1 respectively.
