We construct commutative and noncommutative Bell polynomials and explain how they give rise to Faà di Bruno Hopf algebras. We use the language of incidence Hopf algebras, and along the way provide a ...

Our work group represents the fields of operator algebras and noncommutative geometry in teaching and research. The current focus of our research is structure of C * algebras and more general ...

In this paper, we introduce and study left (right) G-semihereditary rings over any associative ring, and these rings are exactly G-semihereditary rings defined by Mahdou and Tamekkante provided that R ...
