| Feb 18, 2017 at 20:34 | comment | added | wonderich | @Mark Grant, Actually, why do you wrote $0=i^*\alpha\in H^d(A;M)$ instead of $0=i^*\alpha\in H^d(B;M)$? Should it be trivial in the cohomology group of $B$? (Is that the same as trivial in the cohomology group of $A$?) | |

instead $\gamma\in H^d(A/B;M)$
