Étale morphism: Standards, Definition & Inverse function theorem

In algebraic geometry, an étale morphism (French: ) is a morphism of schemes that is formally étale and locally of finite presentation; the étale morphism is connected to the concept of étale covering. This is an algebraic analogue of the notion of a local isomorphism in the complex analytic topology.

What this topic covers Research coverage

Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.

Definition · 16 topics
Inverse function theorem · 9 topics

Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
