Charge Orbits and Moduli Spaces of Black Hole Attractors
Alessio Marrani
We report on the theory of "large" U-duality charge orbits and related "moduli spaces" of extremal black hole attractors in N = 2, d = 4 Maxwell-Einstein supergravity theories with…
Exceptional Reductions
Alessio Marrani, Emanuele Orazi, Fabio Riccioni
Starting from basic identities of the group E8, we perform progressive reductions, namely decompositions with respect to the maximal and symmetric embeddings of E7xSU(2) and then o…
Topics in Cubic Special Geometry
Stefano Bellucci, Alessio Marrani, Raju Roychowdhury
We reconsider the sub-leading quantum perturbative corrections to N=2 cubic special Kaehler geometries. Imposing the invariance under axion-shifts, all such corrections (but the im…
Two-Center Black Holes Duality-Invariants for stu Model and its lower-rank Descendants
Sergio Ferrara, Alessio Marrani, Emanuele Orazi +2
We classify 2-center extremal black hole charge configurations through duality-invariant homogeneous polynomials, which are the generalization of the unique invariant quartic polyn…
Split Attractor Flow in N=2 Minimally Coupled Supergravity
Sergio Ferrara, Alessio Marrani, Emanuele Orazi
We classify the stability region, marginal stability walls (MS) and split attractor flows for two-center extremal black holes in four-dimensional N=2 supergravity minimally coupled…
Matrix Norms, BPS Bounds and Marginal Stability in N=8 Supergravity
Sergio Ferrara, Alessio Marrani
We study the conditions of marginal stability for two-center extremal black holes in N-extended supergravity in four dimensions, with particular emphasis on the N=8 case. This is a…
