Higher limits over the fusion orbit category
Ergün Yalçın
Bilkent University, Türkiye
An homology decomposition of a discrete group is sharp if certain higher limits vanish. For the subgroup decomposition these higher limits are either over the orbit category or over the fusion orbit category of a discrete group. I will introduce these categories and discuss how the higher limits over an orbit category can be calculated. At the end, I will state some results for the vanishing of higher limits over the fusion orbit category of a discrete group.
