Considering a stationary stochastic process with independent increments (Lévy process), we study the probability of the first exit from a strip through its upper boundary. We find the two-sided inequalities for this probability under various conditions on the process.

随机过程的双边边界交叉问题中的不等式

考虑具有独立增量的平稳随机过程（Lévy 过程），我们研究了从带状体第一次通过其上边界退出的概率。我们在过程的各种条件下找到此概率的两侧不等式。
