On the stability of non-supersymmetric supergravity solutions
We examine the stability of some non-supersymmetric supergravity solutions
that have been found recently. The first solution is AdS_5 X M_6, for M_6 an
stretched CP^3. We consider breathing and squashing mode deformations of the
metric, and find that the solution is stable against small fluctuations of this
kind. Next we consider type IIB solution of AdS_2 X M_8, where the compact
space is a U(1) bundle over N(1,1). We study its stability under the
deformation of M_8 and the 5-form flux. In this case we also find that the
solution is stable under small fluctuation modes of the corresponding
deformations.Comment: 11 page
