The generalized upper box dimension
Lipeng Wang, Wenxia Li
We introduce the generalized upper box dimension which is defined for any set, whether the set is bounded or unbounded. We study basic properties of the generalized upper box dimen…

Spectrality of Infinite Convolutions and Random Convolutions
Wenxia Li, Jun Jie Miao, Zhiqiang Wang
In this paper, we explore spectral measures whose square integrable spaces admit a family of exponential functions as an orthonormal basis.Our approach involves utilizing the integ…
