Fano's theorem
WebTHEOREM 1.8. Fano’s geometry consists of exactly seven points and seven lines. Proof: From Axioms 1 and 2, there are at least three points in the geometry, while from Axiom 3 there is at least a fourth point, as symbolized in Figure (a). By Axiom 4, there must be lines joining this fourth point and each of the existing points (Figure b), and ... WebThis is a special kind of Fano fibration. Fano fibrations and more generally Fano type fibrations appear naturally when studying uniruled varieties, and also in the context of moduli theory. Theorem (Mori-Prokhorov) Let X be a 3-fold with terminal singularities, and f : X !Z be a Mori fibre space; if Z is a surface, then Z has canonical sing;

WebAfter the second proof, its relation to Fano's argument is discussed, together with questions of uniqueness, bounded media, source origins, and density de-pendence of the cross sections. (See also Refs. (9) and (10).) REVISED STATEMENT OF THE THEOREM, AND FANO'S PROOF In what follows, we use "fluence" rather than the more accurate but longer WebThe idea is just that you integrate the reflection coefficient (which depends on frequency) over the bandwidth of interest, get an overall reflection coefficient. I think you need to look at the first paragraph of page 5! (by the way, I'm reading Fano's report and it's a treat to read, a little old-school, but very clear in how it leads me as ...
WebSolution:Theorem 1.8 declares that there are exactly seven lines in the geometry. 10. Explain why C(7,2) does not give the number of lines in Fano's geometry, but can be used to derive the correct number of lines. Solution:C(7,2) = 21, counts the number of pairs of points in the geometry. While each pair does determine a line, it is not true ...
