特征p的局部域上稀疏多项式的零点
Zeros of sparse polynomials over local fields of characteristic p
摘要:
设K是F_q((T)),或更一般地,任何特征为p的域,其赋值具有q个元素的有限剩余域。则在K[x]中具有k+1个非零系数的多项式f(x)在K中最多有q^k个不同的零。我们还得到了K上至多d次零点个数的最佳可能界。
英文摘要:
Let K be F_q((T)), or more generally any field of characteristic p equipped with a valuation having a finite residue field of q elements. Then a polynomial f(x) in K[x] having k+1 nonzero coefficients has at most q^k distinct zeros in K. We also obtain the best possible bound for the number of zeros of degree at most d over K.
