On Fourier multipliers with rapidly oscillating symbols
D. Stolyarov Saint Petersburg State University
Abstract:
We provide asymptotically sharp bounds for the $L_p$ norms of the Fourier multipliers with symbols $e^{i\lambda \varphi(\xi/|\xi|)}$, where $\lambda\in \mathbb{R}$ is a large parameter.
Keywords:
Fourier multiplier, oscillatory integral.
