ABSTRACT

We construct new solutions of the vacuum Einstein field equations with cosmological constant. These solutions describe spacetimes with non-trivial topology that are asymptotically dS, AdS or flat. For a negative cosmological constant these solutions are NUT charged generalizations of the topological black hole solutions in higher dimensions. We also point out the existence of such NUT charged spacetimes in odd dimensions and we explicitly construct such spaces in 5 and 7 dimensions. The existence of such spacetimes with non-trivial topology is closely related to the existence of the cosmological constant. Finally, we discuss the global structure of such solutions and possible applications in string theory. Comment: latex, 30 pages, added references

    • "In particular this means that in the 4d case, the boundary is nothing more than AdS 3 , and more generally, AdS 3 × S d−4 for d > 4. Due to its connection with the Kerr-AdS solution, this boundary can be thought of as an Einstein static universe which rotates effectively at the speed of light [25]. The obtained solutions (5) are a particular case of the 'nutty' spacetimes constructed in [26] [27]. To see this, let us specify to four dimensions and consider the hyperbolic Taub-NUT-AdS metric [28] "

    ABSTRACT: We apply the hyperboloid membrane limit to the general Kerr-AdS metrics and their recently studied super-entropic cousins and obtain a new class of rotating black holes, for which the rotational parameters in multiple directions attain their maximal value---equal to the AdS radius. These new solutions have a potential application in the description of holographic fluids with vorticity. They also possess interesting thermodynamic properties: we show that---despite the absence of Misner strings---the Bekenstein--Hawking entropy/area law is still violated, raising a question about the origin of this violation.

    • "is Einstein, this perturbation corresponds to the linearization of the higher-dimensional Taub- NUT solutions of Refs. [27] [28]. For d = 6, the algebraic type of some of these solutions was discussed in Ref. [29], where they were shown to be type D in the classification of Ref. [4]. "

    ABSTRACT: We study algebraically special perturbations of a generalized Schwarzschild solution in any number of dimensions. There are two motivations. First, to learn whether there exist interesting higher-dimensional algebraically special solutions beyond the known ones. Second, algebraically special perturbations present an obstruction to the unique reconstruction of general metric perturbations from gauge-invariant variables analogous to the Teukolsky scalars and it is desirable to know the extent of this non-uniqueness. In four dimensions, our results generalize those of Couch and Newman, who found infinite families of time-dependent algebraically special perturbations. In higher dimensions, we find that the only regular algebraically special perturbations are those corresponding to deformations within the Myers-Perry family. Our results are relevant for several inequivalent definitions of "algebraically special".

    • "Its uncharged Taub-NUT version has been used to construct higher dimensional gravitational monopoles [30]. This asymptotically conical space was shown to have a 'balloon' type instability [31] where one of the spheres inflates at the expense of the other. "

    ABSTRACT: Starting from a metric Ansatz permitting a weak version of Birkhoff's theorem we find static black hole solutions including matter in the form of free scalar and p-form fields, with and without a cosmological constant \Lambda. Single p-form matter fields permit multiple possibilities, including dyonic solutions, self-dual instantons and metrics with Einstein-Kaelher horizons. The inclusion of multiple p-forms on the other hand, arranged in a homogeneous fashion with respect to the horizon geometry, permits the construction of higher dimensional dyonic p-form black holes and four dimensional axionic black holes with flat horizons, when \Lambda<0. It is found that axionic fields regularize black hole solutions in the sense, for example, of permitting regular -- rather than singular -- small mass Reissner-Nordstrom type black holes. Their cosmic string and Vaidya versions are also obtained.
