The functor of complex characters of finite groups

Mehmet Arslan, Olcay Coşkun

We determine the structure of the fibered biset functor sending a finite group $G$ to the complex vector space of complex valued class functions of $G$ . Previously, it is studied a…

Obstructions for gluing biset functors

Olcay Coskun, Ergun Yalcin

We develop an obstruction theory for the existence and uniqueness of a solution to the gluing problem for a destriction functor and apply it to some well-known biset functors. The…

Fibered $p$ -biset functor structure of the fibered Burnside rings

Olcay Coşkun, Deniz Yılmaz

We determine the composition factors of the $A$ -fibered Burnside functor $k B^{A}$ for $p$ -groups over a field $k$ of characteristic $q$ with $q \neq = p$ and cyclic fiber group $A$ . We…
