WebOct 25, 2024 · There are 3 types of DVR: equal characteristic 0 or p, and mixed characteristic. In the equal characteristic 0 case, we can’t have such an example, as the finite flat group scheme has to be finite étale, and hence the specialization map induces an isomorphism, so the family of groups is essentially constant (appropriately interpreted). WebThe scheme-theoretic intersection T ′ = T ∩ D ( G) is a maximal k -torus of D ( G), and we claim that a central extension exists as above if and only if the pullback central extension T ~ × T T ′ of T ′ by Z is split as such, in which case we claim that D ( G ~) → D ( G) is an isomorphism (so D ( G ~) is simply connected) and that ...
