We discuss the Attractor Equations of N = 2, d = 4 supergravity in an extremal black hole background with arbitrary electric and magnetic fluxes (charges) for field-strength two-forms. The effective… (More)

The general solutions of the radial attractor flow equations for extremal black holes, both for non-BPS with non-vanishing central charge Z and for Z = 0, are obtained for the so-called stu model,… (More)

We generalize the description of the d = 4 Attractor Mechanism based on an effective black hole (BH) potential to the presence of a gauging which does not modify the derivatives of the scalars and… (More)

We study the “flat” directions of non-BPS extremal black hole attractors for N = 2, d = 4 supergravities whose vector multiplets’ scalar manifold is endowed with homogeneous symmetric special Kähler… (More)

We analyze the Hessian matrix of the black hole potential of N = 8, d = 4 supergravity, and determine its rank at non-BPS critical points, relating the resulting spectrum to non-BPS solutions (with… (More)

We report on recent results in the study of extremal black hole attractors in N = 2, d = 4 ungauged Maxwell-Einstein supergravities. For homogeneous symmetric scalar manifolds, the three general… (More)

These lectures provide a pedagogical, introductory review of the so-called Attractor Mechanism (AM) at work in two different 4-dimensional frameworks: extremal black holes in N = 2 supergravity and N… (More)

We report on recent advances in the study of critical points of the “black hole effective potential” VBH (usually named attractors) of N = 2, d = 4 supergravity coupled to nV Abelian vector… (More)

We express the d = 4, N = 2 black hole effective potential for cubic holomorphic F functions and generic dyonic charges in terms of d = 5 real special geometry data. The 4d critical points are… (More)
