Poncelet polygon density conjecture for pairs of conics
Poncelet polygon density conjecture for pairs of conics
Let be a finite field of characteristic greater than , and let be an integer coprime to . Let denote the set of ordered pairs of smooth conics satisfying the Poncelet -gon condition, and let denote the space of ordered pairs of smooth conics. For an integer , write for the number of divisors of other than and .
Poncelet polygon density conjecture. The density satisfies
This conjecture extends the proved odd- asymptotic to even integers, including a corrected version of Chipalkatti's tetragon conjecture. The preceding results establish the corresponding asymptotic for odd coprime to , while the general case remains open.
