Manin conjecture

In mathematics, the Manin conjecture describes the conjectural distribution of rational points on an algebraic variety relative to a suitable height function. It was proposed by Yuri I. Manin and his collaborators[1] in 1989 when they initiated a program with the aim of describing the distribution of rational points on suitable algebraic varieties.

Rational points of bounded height outside the 27 lines on Clebsch's diagonal cubic surface.

Conjecture

Their main conjecture is as follows. Let be a Fano variety defined over a number field , let be a height function which is relative to the anticanonical divisor and assume that is Zariski dense in . Then there exists a non-empty Zariski open subset such that the counting function of -rational points of bounded height, defined by

for , satisfies

as Here is the rank of the Picard group of and is a positive constant which later received a conjectural interpretation by Peyre.[2]

Manin's conjecture has been decided for special families of varieties,[3] but is still open in general.
