In finite geometry, the Fano plane (after Gino Fano) is a finite projective plane with the smallest possible number of points and lines: 7 points and 7 lines, with 3 points on every line and 3 lines through every point.

WebThe following theorem is the main result of this note. Theorem 1.4. Let X be a Fano variety of dimension n with at worst isolated quotient singularities. If iX > max{ n2 + 1, 2n 3 }, then ρX = 1. Consider a smooth Fano variety X. WebFor this theorem, the condition on the Picard number is crucial because a smooth Fano symmetric variety with higher Picard number may have no Kähler–Einstein metrics. For example, the blow-up of the wonderful compactification of Sp ( 4 , C ) along the closed orbit does not admit any Kähler–Einstein metrics (see Example 5.4 of [ 16 ]).

Suppose 1 and 2 are distinct lines in Fano’s Geometry. Axiom 5 says there is at least one point on both of them. If points P and P are on both 1 and 2 then Axiom 4 is contradicted as there are two lines on both P and P . 3.
