Scheme-theoretic intersection: Products, Proper intersection & Overview

In algebraic geometry, the scheme-theoretic intersection of closed subschemes X, Y of a scheme W is X × W Y {\displaystyle X\times _{W}Y} , the fiber product of the closed immersions X ↪ W , Y ↪ W {\displaystyle X\hookrightarrow W,Y\hookrightarrow W} . It is denoted by X ∩ Y {\displaystyle X\cap Y} .

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.

Overview · 14 topics
Proper intersection · 6 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.
