Abstract

In previous sections we considered the N = 2, d = 4 Maxwell–Einstein supergravity theory (MESGT) coupled to nV Abelian vector supermultiplets, and we have seen explicitly how the attractor mechanism works in the moduli space M nV of such a theory, in relation to the (covariant derivatives of the) central charge of the N = 2 superalgebra. We mainly used a fundamental feature of N = 2, d = 4, nV -fold MESGT, namely the symplectic, special Kähler–Hodge geometry exhibited by M nV .
