THE GAUGE DUAL OF GAUGED ${\mathcal N}=8$ SUPERGRAVITY THEORY
The most general SU(3) -singlet space of gauged [Formula: see text] supergravity in four-dimensions is studied recently. The SU(3) -invariant six scalar fields are realized by six real four-forms. A family of holographic [Formula: see text] supersymmetric RG flows on M2-branes in three-dimensions is described. This family of flows is driven by three independent mass parameters from the [Formula: see text] theory and is controlled by two IR fixed points, [Formula: see text]-invariant one and [Formula: see text]-invariant one. The generic flow with arbitrary mass parameters is [Formula: see text] supersymmetric and reaches to the [Formula: see text] fixed point where the three masses become identical. A particular [Formula: see text] supersymmetric SU(3) -preserving RG flow from the [Formula: see text]-invariant fixed point to the [Formula: see text]-invariant fixed point is also discussed.
