On Static Black Holes in Type IIA on a Nearly-Kahler Coset    [PDF]

Tetsuji Kimura

We study static black hole solutions in four-dimensional N=2 gauged supergravity with one vector multiplet and one hyper-tensor multiplet. This is derived from massive type IIA theory compactified on the nearly-Kahler coset space G2/SU(3). It is well-known that the Romans' mass parameter yields the Stuckelberg-type deformation of the gauge field strengths in the four-dimensional system. This deformation requires that all the (covariant) derivatives of the scalar fields must vanish and the two-form field is closed. It turns out that AdS vacua or Schwarzschild-AdS black holes are only allowed as the static solutions.
