AI总结:

本文提出了一种针对局部域上有限型平面曲线扩展算子正方形函数的计数方法,得出了关于多项式形式曲线的新估计结果。

摘要:

本文研究了有限型平面曲线在欧几里得弧长测度下的扩展算子的正方形函数。我们证明了对于形式为(T,ϕ(T))的曲线,其中ϕ(T)是一个次数至少为2的多项式,有新的结果。这包括由单项式ϕ(T)=T^k(k≥3)给出的新估计,这些估计在所有特征与k互质的局部域上是均匀的。我们方法的关键是对二阶差分多项式及其在局部域中的几何进行系统分析。

英文摘要:

In this paper, we study square functions for extension operators over finite-type, planar curves endowed with the Euclidean arclength measure. We prove new results for curves of the form $(T,ϕ(T))$ where $ϕ(T)$ is a polynomial of degree at least 2. This includes new estimates for such curves given by monomials $ϕ(T) = T^k$ for $k \geq 3$ which are uniform over all local fields whose characteristic is coprime to \(k\). Key to our approach is a systematic analysis of the second order differencing polynomial and its geometry in local fields.
