Gathering different results from singularity theory, geometry and combinatorics, we show that the spectrum at infinity of a tame Laurent polynomial counts (weighted) lattice points in polytopes. We deduce an effective algorithm in order to compute the Ehrhart polynomial of a simplex containing the origin as an interior point.

多项式的Ehrhart多项式和Laurent多项式的无穷大
从奇异性理论,几何学和组合学获得了不同的结果,我们表明,驯服的Laurent多项式在无穷远处的光谱计数了多表位中的(加权)晶格点。我们推导了一种有效的算法,以计算包含原点作为内部点的单纯形的Ehrhart多项式。
