Abstract.

 We introduce a constant γ m,n (D) attached to a central division algebra D over a number field which is a generalization of the Hermite–Rankin constant. Geometrically, γ m,n (D) equals the maximum of minimal twisted heights of rational points of a generalized Brauer–Severi variety. We will deduce a duality result, an analog of Rankin’s inequality and an upper estimate for γ m,n (D).
