We show that a global holomorphic section of restricted to a closed complex subspace has an interpolant if and only if it satisfies a set of moment conditions that involves a residue current associated with a locally free resolution of . When X is a finite set of points in this can be interpreted as a set of linear conditions that a function on X has to satisfy in order to have a polynomial interpolant of degree at most d.

多项式插值和剩余电流
我们证明了一个全局全纯截面受限于一个封闭的复子空间有一个插值当且仅当它满足一组矩条件,这些条件涉及与局部自由分辨率相关的残余电流. 当X是这可以解释为X上的函数必须满足的一组线性条件,以便具有最多d次的多项式插值。
