The ideals of the slice Burnside p-biset functor
Ibrahima Tounkara
Let G be a finite group and K be a field of characteristic zero. Our purpose is to investigate the ideals of the slice Burnside functor KΞ. It turns out that they are the subfuncto…

On the T-slices of a finite group
Ibrahima Tounkara
A slice (G, S) of finite groups is a pair consisting of a finite group G and a subgroup S of G. In this paper, we show that some properties of finite groups extend to slices of fin…
