On a constant arising in Manin's conjecture for del Pezzo surfaces


Derenthal, U (2007). On a constant arising in Manin's conjecture for del Pezzo surfaces. Mathematical Research Letters, 14(3):481-489.

Abstract

For split smooth Del Pezzo surfaces, we analyse the structure of the effective cone and prove a recursive formula for the value of alpha, appearing in the leading constant as predicted by Peyre of Manin's conjecture on the number of rational points of bounded height on the surface. Furthermore, we calculate alpha for all singular Del Pezzo surfaces of degree at least 3.
