vanishing higher cohomology group for property T group?
@BenWieland, I checked the references you mentioned, but I do not know why the group mentioned by YCor is of type FP. Could you please explain this? |

@BenWieland, thanks, I would check that. |

@BenWieland, could you give me a reference why the group mentioned by YCor has nontrivial $H^2(G, \mathbb{Z}G)$? |

@YCor, in Ben's answer above, -3 paragraph, maybe there is some misunderstanding? |

@YCor, could you give me the reference on the property T group $G$ you mentioned such that $H^2(G;\mathbb{Z}G)$ is nontrivial? Thanks. |

@IgorBelegradek, I am not able to download the paper you mentioned right now, if I understand your remark correctly, you mean there exists a property $T$ group $G$ with $H^2(G, \mathbb{Z})\neq 0$? |

@YCor, you mean for n=2, $G=SL_3(\mathbb{Z})$, the cohomology group vanishes? |

Thanks, I did not realize this simple observation. |
