Within the extremal black hole attractors arising in ungauged N > 1-extended Maxwell Einstein supergravity theories in 3+ 1 space-time dimensions, we provide an overview of the stratiﬁcation of the electric-magnetic charge representation space into “large” orbits and related “moduli spaces”, under the action of the (continuous limit of the) non-compact U-duality Lie group. While each “large” orbit of the U-duality supports a class of attractors, the corresponding “moduli space” is the proper subspace of the scalar manifold spanned by those scalar ﬁelds on which the Attractor Mechanism is inactive. We present the case study concerning N = 2 supergravity theories with symmetric vector multiplets’ scalar manifold, which in all cases (with the exception of the minimally coupled models) have the electric-magnetic charge representation of U-duality ﬁtting into a reduced Freudenthal triple system over a cubic (simple or semi-simple) Jordan algebra.

Reports on this Submission
This is a summary/short review of aspects of the black hole attractor mechanism and the classification of duality orbits of BH charges in N=2 D=4 ungauged supergravity. Most of this dates back to 2013 and (much) earlier. It can work as a short summary with convenient pointers to the literature. It matches with the topic of the associated conference.
