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…

Classifying Slice-Regular Polynomials via Group Actions on the Twistor Space
Chunlin Liu, Giovanni Moreno, Haipan Shi
We study the equivalence classes of slice-regular functions on a symmetric slice domain , and of their subclass made of polynomial slice-regular functions,…
