2 0 $begingroup$ Let $G$ be a finite group, $H$ a subgroup and $N$ a normal subgroup. Let $chi$ be a representation of $HN/N$. Does $$Ind_{HN}^G Inf_{HN/N}^{HN} chi = Inf_{G/N}^G Ind_{HN/N}^{G/N} chi$$ always hold? Here $Ind$ and $Inf$ are the induction and inflation functors. If this isn't true, are there any simple sufficient conditions for it to hold (possibly with a sketch proof/reference)? reference-request finite-groups representation-theory share | cite | improve this question asked Feb 9 '17 at 14:33 Matt B Matt B 2,828 1 6 16 ...
