An obstruction to lifting schemes to spectral schemes

Robert Szafarczyk

$δ^$ -rings are a globalization of $δ$ -rings. Motivated by their application to obstructing spectral lifts, we develop the theory of animated $δ^$ -rings. They extend the discr…

We characterise Dedekind rings among not necessarily Noetherian domains by a property of their module homomorphisms. Our proof relies on a homological algebra argument.
