Author: Olcay Coşkun Title: Ring of subquotients of a finite group I: Linearization Abstract: We introduce the ring of subquotients of a finite group. As an abelian group, it is free on the set of conjugacy classes of subquotients of the group. The ring of subquotients extends the Burnside ring integrally and there is a linearization map with range the Grothendieck ring of the Mackey algebra. Status: to appear J. Algebra.
