复曲线上测度的卷积估计

Convolution estimates for measures on some complex curves

Hyunuk Chung, Seheon Ham

摘要:

我们考虑复曲线上测度的卷积算子。我们在这里考虑的措施是一个模拟的仿射弧长措施真正的曲线。通过修改一个组合参数称为能带结构参数,我们证明了(近)最佳洛伦兹空间估计。这包括作为特殊情况的最优强型估计。我们在这里考虑的复曲线是在\cite{BH}中为复曲线的傅立叶限制估计所考虑的复曲线。

英文摘要:

We consider the convolution operator for a measure supported on complex curves. The measure which we consider here is an analogue of the affine arclength measure for real curves. By modifying a combinatorial argument called the band structure argument, we prove the (nearly) optimal Lorentz space estimates. This includes the optimal strong type estimates as special cases. The complex curves we consider here are the ones considered for the Fourier restriction estimates for complex curves in \cite{BH}.
