Abstract

We generalize central-charge relations and differential identities of N = 2 special geometry to N extended supergravity in any dimension 4 ≤ D < 10, and p-extended objects. We study the extremization of the ADM mass per unit of p-volume of BPS extended objects. Runaway solutions for a "dilaton" degree of freedom leading to a vanishing result are interpreted as BPS extremal states having vanishing Bekenstein–Hawking entropy.
