On factorial reciprocals in Cantor sets

Kehao Lin, Yufeng Wu, Siyu Yang

Let $C$ be the middle-third Cantor set. We show that \[\left\{\frac{1}{n!}: n\in\mathbb{N}\right\}\cap C=\left\{1, \frac{1}{5!}\right\}.\] This answers a question recently posed by…

Efficient and accurate computation to the $φ$ -function and its action on a vector

Siyu Yang, Dongping Li

In this paper, we develop efficient and accurate algorithms for evaluating $φ (A)$ and $φ (A) b$ , where $A$ is an $N \times N$ matrix, $b$ is an $N$ dimensional vector and $φ$ is the f…
