稀疏多项式的值集

Value sets of sparse polynomials

Igor E. Shparlinski, Jose Felipe Voloch

摘要:

当p是素数时,我们得到了p元有限域上F_p[X]中稀疏多项式f的值集f(F_p)的大小的一个新的下界.这个界在次数上是一致的,并且依赖于f的单项式项的次数和这些项的个数的一些自然算术性质。我们的结果比从f(F_p)中单个值的重数界中得到的结果更强。

英文摘要:

We obtain a new lower bound on the size of value set f(F_p) of a sparse polynomial f in F_p[X] over a finite field of p elements when p is prime. This bound is uniform with respect of the degree and depends on some natural arithmetic properties of the degrees of the monomial terms of f and the number of these terms. Our result is stronger than those which canted be extracted from the bounds on multiplicities of individual values in f(F_p).
