We consider domains $D\subseteq\mathbb R^n$ with $C^1$ boundary and study the following question: For what domains $D$ does the Fourier transform $\widehat{1_D}$ of the characteristic function $1_D$ belong to $L^p(\mathbb R^n)$?
Keywords:
harmonic analysis, domain with smooth boundary, Fourier transform of a characteristic function.
