Programmieren von Mikrocomputernase, each .-module can thus also be seen as an .-module with an additional structure. We prove that the effective descent morphisms of rings are exactly the . ones: the injective morphisms, which remain injective when tensored with whatever .-module. The descent theorem for rings implies an analogous result for algebras.

This link will make it possible to combine algebraic and topological aspects in the infinite-dimensional Galois theory of fields, but also in the Galois theory of rings.

The Galois Theorem of Grothendieckhe quotients of Gal[. : .], which is finite and viewed here as acting on itself. It is a classical result of the theory of group actions that these quotients are themselves in bijection with the subgroups of Gal[. : .].
