Spin-2 universal minimal solutions on type IIA and IIB supergravity.

In this paper, we consider the spin-2 field perturbations of four families of supergravity solutions. These include AdS₅ and AdS₇ backgrounds of type IIA as well as AdS₄ and AdS₆ backgrounds of Type IIB. As the main result, we show that, in all the cases, there is a solution given by a combination of the warp factors. We also find the respective mass spectra. We analyze the normalizability of the solutions and identify the superconformal multiplets dual to them. [ABSTRACT FROM AUTHOR]
