| “ | ... if A and B are subvarieties of a non-singular variety X, the intersection product A.B should be an equivalence class of algebraic cycles closely related to the geometry of how A∩B, A and B are situated in X. Two extreme cases have been most familiar. If the intersection is proper, i.e. dim(A∩B) = dim A + dim B − dim X, then A.B is a linear combination of the irreducible components of A∩B, with coefficients the intersection multiplicities. At the other extreme, if A = B is a non-singular subvariety, the self-intersection formula says that A.B is represented by the top Chern class of the normal bundle of A in X. | ” |

Disambiguation/ move
Moved this page to create a disambiguation page with Intersection theory (critical theory) —The preceding unsigned comment was added by Fokion (talk • contribs) 19:20, August 23, 2007 (UTC).
Too much focus on examples
Coming to the article as a reader lacking information, there is very little in it that actually describes intersection theory, and a lot of math (presumably) from it. Questions knowledgable editors might answer in the article: What is intersection theory, beyond a branch of algebraic theory? How did it start, or become identified as a separate branch? Who are the notable historical people involved in it, is it just Bézout? What other areas of mathematics and science has it been important for? What is its most important findings? (Perhaps the current contents of the article is a summary of that last, could it be structured better to make that more clear?) Kloddall (talk) 13:01, 26 May 2021 (UTC)
