Commutativity and ideals in category crossed products

Öinert, Johan LU and Lundström, P (2010) In Proceedings of the Estonian Academy of Sciences 59(4). p.338-346
Abstract
In order to simultaneously generalize matrix rings and group graded crossed products, we introduce category crossed products. For such algebras we describe the centre and the commutant of the coefficient ring. We also investigate the connection between on the one hand maximal commutativity of the coefficient ring and on the other hand nonemptiness of intersections of the coefficient ring by nonzero two-sided ideals.
