D-instantons and Black Holes in N=2, D=4 Supergravity
نویسنده
چکیده
We discuss T-duality between the solutions of type II A versus type II B superstrings compactiied on Calabi-Yau threefolds. Within the context of N = 2, D = 4 supergravity eeective Lagrangian, the T-duality transformation is equivalently described by the c-map, which transforms the IIA black hole solutions into the IIB D-instanton solutions. We construct via this mapping a broad class of D-instanton solutions in four dimensions.

Branes in N = 2 , D = 4 supergravity and the conformal field theory limit 1
In this article we summarise the brane solutions (instantons, black holes and strings) in 4 dimensions when embedded in N = 2 supergravity. Like in 10 dimensions these solutions are related by duality transformations (T -duality, c-map). For the case that the graviphoton has no magnetic charge, we discuss the conformal field theory description of the near-horizon geometry. The decoupling of the...
متن کاملStationary Solutions of N = 2 Supergravity
We discuss general bosonic stationary configurations of N = 2, D = 4 supergravity coupled to vector multiplets. The requirement of unbroken supersymmetries imposes constraints on the holomorphic symplectic section of the underlying special Kähler manifold. The corresponding solutions of the field equations are completely determined by a set of harmonic functions. As examples we discuss rotating...
متن کاملBps Black Holes in Gauged N=4, D=4 Supergravity Typeset Using Revt E X 2
We find solutions of the bosonic sector of gauged N=4, D=4 SU(2) × SU(2) supergravity, which represent dilaton black holes with toroidal or spherical event horizons. The axion is consistently truncated, and the gauge group is broken to U(1) × U(1). The spherical black holes carry two electric and two magnetic abelian charges, whereas the toroidal holes have vanishing magnetic charges. The space...

متن کاملModuli Spaces for Four - and Five - Dimensional Black Holes
We propose a universal expression for the moduli metric of a class of four-and five-dimensional black holes which preserve at least four supersymmetries. These include the black holes that are associated with various intersecting branes in ten and eleven dimensions, the electrically charged black holes of N=2 D=5 and N=2 D=4 supergravities with any number of vector multiplets, and dyonic black ...
