Cinzia Bisi (Università di Ferrara) - Invariants and automorphisms for slice regular functions : from some clifford algebras, as the quaternions, to the octonions

Event description

Abstract: Let A be one of the following Clifford algebras : 
$\mathbb{R}_2 \cong \mathbb{H} ,\mathbb{R}_3$, or 
$ A= \mathbb{O}$. 
For the algebra A, the automorphism group Aut(A) and its invariants are well known. In this talk, I will describe the invariants of the automorphism group of the algebra of slice regular functions over A. All the results presented are contained in two preprints , jointly with Joerg Winkelmann (Ruhr-University,Bochum), soon available on Arxiv
