Fuglede's spectral set conjecture for convex polytopes

Rachel Greenfeld, Nir Lev

Let $Ω$ be a convex polytope in $R^{d}$ . We say that $Ω$ is spectral if the space $L^{2} (Ω)$ admits an orthogonal basis consisting of exponential functions. There is a conject…

Spectrality and tiling by cylindric domains

Rachel Greenfeld, Nir Lev

A bounded set $Ω \subset R^{d}$ is called a spectral set if the space $L^{2} (Ω)$ admits a complete orthogonal system of exponential functions. We prove that a cylindric set $Ω$ …
