Multidimensional Fourier Quasicrystals I. Sufficient Conditions

Wayne M. Lawton, August K. Tsikh

We derive sufficient conditions for an atomic measure ${\sum }_{\lambda \in \Lambda }{m}_{\lambda }{\delta }_{\lambda },$ where $\Lambda \subset {\mathbb{R}}^n,$ $m_{\lambda }$ are positive integers, and ${\delta }_{\lambda }$ is the point measure at $\lambda ,$ t…
