Web$\begingroup$ I think the idea of $\mathbb Z_{p}$-extension is the kind of idea that have been around at least implicitly for a long time. Certainly Kronecker and Weber knew explicit descriptions of abelian extensions of CM fields, and from that knowledge, introducing the $\mathbb Z_{p}$-extension is just singling out some particularly interesting extensions. WebApr 11, 2024 · By definition, if C is a category in which each object has finitely many automorphisms, ... are 1 (resp. 0), and the l-adic Galois representation on the (2n)th cohomology group is the nth power of the cyclotomic character. The second part is a consequence of the fact that the cohomology of is generated by algebraic cycle classes. …
