A model structure via orbit spaces for equivariant homotopy
(Springer, 2019-06-26)Let G be discrete group and FF be a collection of subgroups of G. We show that there exists a left induced model structure on the category of right G-simplicial sets, in which the weak equivalences and cofibrations are the ... -
On contractibility of th orbit space of a G-poset of Brauer pairs
(ElsevierAcademic Press, 1999-02-15)Given ap-blockbof a finite groupG, we show that theG-poset of Brauer pairs strictly containing (1,b) has contractibleG-orbit space. A similar result is proved for certainG-posets ofp-subgroups. Both results generalise P. ... -
