April 30, 2024 -Negligible cohomology (Matthew Gherman, Caltech)
Negligible cohomology (Matthew Gherman, Caltech)
For a finite group G, a G-module M, and a field F, an element u in H^d(G,M) is negligible over F if for each field extension L/F and every continuous group homomorphism from Gal(L^{sep}/L) to G, u is in the kernel of the induced homomorphism H^d(G,M) to H^d(L,M). Negligible cohomology was first introduced by Serre […]
