Carleson measures, tent embeddings, and Volterra-type integral operators on the unit ball
Xiaofen Lv, Xiaomin Tang, Jani A. Virtanen
In this paper, we establish a sharp comparison between Carleson-cube and Bergman-metric-ball conditions on the open unit ball $\B$ and combine it with a Berezin-type characterizati…

The Uncertainty Principles of Quaternion Fractional Fourier Transform
Ke Cui, Haipan Shi, Xiaomin Tang
In this paper, we mainly establish the uncertainty principle (UP) for a function and its quaternion Fractional Fourier transform (QFrFT), as well as the UP for two QFrFTs. Using th…
