多项式系数Enumeration

Polynomial Coefficient Enumeration

Tewodros Amdeberhan, Richard P. Stanley

摘要:

令$f(x_1,...,x_k)$是域$K$上的多项式。本文考虑$f$的非零系数个数的计数或等于$α\in K^*$的系数个数的计数等问题。例如,如果$K=\ff_q$,则获得作为$n$的函数的$f^n$的等于$α\in \ff_q^*$的系数的数目的矩阵公式。在诸如格路计数和凸多胞体中整数点的计数等方面得到了许多新的结果。

英文摘要:

Let $f(x_1,...,x_k)$ be a polynomial over a field $K$. This paper considers such questions as the enumeration of the number of nonzero coefficients of $f$ or of the number of coefficients equal to $α\in K^*$. For instance, if $K=\ff_q$ then a matrix formula is obtained for the number of coefficients of $f^n$ that are equal to $α\in \ff_q^*$, as a function of $n$. Many additional results are obtained related to such areas as lattice path enumeration and the enumeration of integer points in convex polytopes.
