This is not yet defined in the glossary!--129.70.14.128 (talk) 01:26, 20 November 2007 (UTC)[reply]

The definition of "geometric point" appearing in the glossary requires that the scheme in question be defined over a field. What is the appropriate definition in the general case? 98.243.172.55 (talk) 19:23, 7 December 2013 (UTC)[reply]

A geometric point of X is ${\displaystyle \operatorname {Spec} (k)\to X}$ where k is a separably closed field. -- Taku (talk) 14:17, 17 December 2013 (UTC)[reply]

This page should discuss examples of smooth morphisms

• trivial fibrations
• Hirzebruch surfaces over ${\displaystyle \mathbb {P} ^{1}}$
• scrolls
• vector bundles
• smooth locus of flat families
• etale morphisms

and non-examples, such as

• families of singular varieties
• singular variety over a point
• blowups — Preceding unsigned comment added by 97.122.75.155 (talk) 17:31, 1 August 2017 (UTC)[reply]

This page should discuss how to find the smooth locus of a morphism of schemes ${\displaystyle X\to S}$. — Preceding unsigned comment added by 97.122.75.155 (talk) 05:12, 4 August 2017 (UTC)[reply]

I believe this is a version of Bertini's theorem (no question it's an important thing to cover). -- Taku (talk) 23:20, 8 August 2017 (UTC)[reply]
