\u201cCategorifying induction formulae via divergent series\u201d<\/p>\n
Abstract: We show how to get explicit induction formulae for finite group representations (and more generally for rational Green functors) by summing a divergent series over Dwyer\u2019s subgroup and centralizer decomposition spaces. This results in formulae with rational coefficients. The former space yields a well-known induction formula, the latter yields a new one. As essentially immediate corollaries of the existing literature, we get similar formulae in group cohomology and stable splittings of classifying spaces.<\/p>\n
