I undererstimated the problem of evaluating the transfer on elements of the form $h[G,G]$. Concerning 3: I forgot the additional condition $H = f^{-1}(H')$. | |

| Dec 19, 2011 at 8:42 | comment | added | Martin Brandenburg | This is exactly what I was looking for. Can you give me a hint why 3. is true for the transfer map? I can only prove it when $f$ induces a bijection $H/G \to H'/G'$. | |
