Abstract: Abstract We revisit non-rotating, dyonically charged, and supersymmetric AdS4 black holes, which are solutions of $$ \mathcal{N} $$ N = 2 gauged supergravity with vector- and hyper-multiplets. Uplifting the near horizon solutions to D =… read more here.

Abstract: In this note we give an explicit construction of Sasaki-Einstein metrics on a class of simply connected 7-manifolds with the rational cohomology of the 2-fold connected sum of $S^2\times S^5$. The homotopy types are distinguished… read more here.

Abstract: We show that a connection with skew-symmetric torsion satisfying the Einstein metricity condition exists on an almost contact metric manifold exactly when it is D-homothetic to a cosymplectic manifold. In dimension five, we get that… read more here.

Abstract: We study the transverse Kähler structure of the Sasaki–Einstein space [Formula: see text]. A set of local holomorphic coordinates is introduced and a Sasakian analogue of the Kähler potential is given. We investigate deformations of… read more here.

Abstract: We investigate the deformations of the Sasaki–Einstein structures of the five-dimensional spaces T 1 , 1 and Y p , q by exploiting the transverse structure of the Sasaki manifolds. We consider local deformations of… read more here.
