Center of double extension regular algebras of type (14641)

Abstract

In this paper we compute the center and, in several cases, central subalgebras of double Ore extensions of type (14641) under suitable restrictions on the defining parameters. Part of the analysis is supported by computations in SageMath. As an application, we provide new examples related to the Zariski cancellation problem.
