A Uniform L∞ Estimate of the Smoothing Operators Related to Plane Curves
Published online by Cambridge University Press: 20 November 2018
Abstract
In dealing with the spectral synthesis property for a plane curve with nonzero curvature, a key step is to have a uniform L∞ estimate for some smoothing operators related to the curve. In this paper, we will show that the same L∞ estimate holds true for a plane curve that may have zero curvature.
