丢番图不等式与拟代数闭域

Diophantine inequalities and quasi-algebraically closed fields

Craig V. Spencer, Trevor D. Wooley

摘要:

考虑次数$d$的形式$g(x_1,...,x_s)$,其系数在与有限域$F_q$相关联的分数域$F_q(t)$的完备化$F_q((1/t))$中。我们建立,只要$s>d^2$,那么形式$g$采取任意小的值为非零参数$x\in F_q[t]^s$。我们提供了相关的结果,涉及分配模$F_q[t]$的问题,和类似的结论一般的拟代数闭域。

英文摘要:

Consider a form $g(x_1,...,x_s)$ of degree $d$, having coefficients in the completion $F_q((1/t))$ of the field of fractions $F_q(t)$ associated to the finite field $F_q$. We establish that whenever $s>d^2$, then the form $g$ takes arbitrarily small values for non-zero arguments $x\in F_q[t]^s$. We provide related results for problems involving distribution modulo $F_q[t]$, and analogous conclusions for quasi-algebraically closed fields in general.
