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 $f:\hat{I}\text{c◯}\to \mathbb{H}$ on a symmetric slice domain $\hat{I}\text{c◯}$, and of their subclass made of polynomial slice-regular functions,…
