论文摘要
我们证明了以下语句的定量版本：如果1+1维波方程的解具有空间紧凑的支持，并且主要由正频率组成，则它必须具有重要的高频组件。对于3+1维波方程式证明了类似的结果。
We prove quantitative versions of the following statement: If a solution of the 1+1-dimensional wave equation has spatially compact support and consists mainly of positive frequencies, then it must have a significant high-frequency component. Similar results are proven for the 3+1-dimensional wave equation.
