论文摘要
我们开发了通过取指指数riesz基地的工会来构建指数riesz基地的新方法。这些方法分别基于频率集和域的工会，因此可以轻松构造。再加上说明我们方法的示例，我们还提供了几个示例，显示了指数riesz基础的微妙性质。
We develop new methods for constructing exponential Riesz bases by taking unions of exponential Riesz bases. These methods are based on taking unions of frequency sets and domains respectively and therefore allow easy construction. Together with examples that illustrate our methods, we also provide several examples showing the delicate nature of exponential Riesz bases.
