Differential étale extensions and differential modules over differential rings

Advances in Applied Mathematics, 2016
An extension of rings \(R/F\) is defined to be formally étale if it satisfies the following lifting property: For all surjective homomorphisms of \(F\)-algebras \(f:A\to S\) whose kernel \(I=\mathrm {ker}(f)\) satisfies \(I^2=0\) and all \(F\)-algebra homomorphisms \(g: R\to S\) there is a lifting of \(g\) to \(h: R\to A\), i.e.

Differential Modules and Ramification

2004
Differential modules and ramification is the subject of this chapter. With regard to the principal properties of differential modules, we refer to chapter 16 of Eisenbud’s book [63], and add some more results in section 1. After dealing with norms and traces in section 2, we introduce the notion of formally unramified and unramified extensions of rings

Business Module Differentiation

2007
SINA, SOHU, and NETEASE have been regarded as the most successful general Web portals in the Chinese market. However, they have quite different strategies in their business modules, which makes them quite different in terms of their revenue constitution. What are the major reasons and what will be the future direction for Chinese Web portals?
