Jeremy Schwend

摘要:

给出了$\mathbb{R}^3$中一类二元多项式沿图的局部平均值为限制弱型$(p,q)$的$(p,q)$的精确值域,其中超曲面具有欧氏曲面测度.我们得出这些结果,使用非振荡,几何方法,模型类的多项式轴承强连接到一般的真实分析的情况下。

英文摘要:

We find the precise range of $(p,q)$ for which local averages along graphs of a class of two-variable polynomials in $\mathbb{R}^3$ are of restricted weak type $(p,q)$, given the hypersurfaces have Euclidean surface measure. We derive these results using non-oscillatory, geometric methods, for a model class of polynomials bearing a strong connection to the general real-analytic case.
