style='font-size:12.0pt;font-family:Arial'>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 (sections) of the group and extends the well-known
Burnside ring. The talk will start by introducing the category of bisets and
some related functor categories which form our general framework.</span></font><font
