We study holographic RG flow solutions within four-dimensional \(N=4\) gauged supergravity obtained from type IIA and IIB string theories compactified on \(T^6/\mathbb {Z}_2\times \mathbb {Z}_2\) orbifold with gauge, geometric and non-geometric fluxes. In type IIB non-geometric compactifications, the resulting gauged supergravity has \(ISO(3)\times ISO(3)\) gauge group and admits...

We holographically study supersymmetric deformations of \(N=3\) and \(N=1\) superconformal field theories in three dimensions using four-dimensional \(N=4\) gauged supergravity coupled to three-vector multiplets with non-semisimple \(SO(3)\ltimes (\mathbf {T}^3,\hat{\mathbf {T}}^3)\) gauge group. This gauged supergravity can be obtained from a truncation of 11-dimensional...

We study fully supersymmetric AdS6 vacua of half-maximal N = (1, 1) gauged supergravity in six space-time dimensions coupled to n vector multiplets. We show that the existence of AdS6 backgrounds requires that the gauge group is of the form G′ × G″ ⊂ SO(4, n) where G′ ⊂ SO(3, m) and G″ ⊂ SO(1, n − m). In the AdS6 vacua this gauge group is broken to its maximal compact subgroup SO...

We construct a new N = 4 non-semisimple gauged supergravity in three dimensions with E 6(2) /SU(6) × SU(2) scalar manifold and SO(4) ⋉ T 6 gauge group. Depending on the values of the gauge coupling constants, the theory admits both the maximally supersymmetric AdS 3 vacuum preserving SO(4) gauge symmetry and half-supersymmetric domain walls with unbroken SO(4) symmetry. We give...

We study supersymmetric AdS 4 × Σ2 and AdS 3 × Σ3 solutions in half-maximal gauged supergravity in six dimensions with SU(2) R × SU(2) gauge group. The gauged supergravity is obtained by coupling three vector multiplets to the pure F(4) gauged supergravity. The SU(2) R R-symmetry together with the SO(3) ∼ SU(2) symmetry of the vector multiplets are gauged. The resulting gauged...

We study AdS 5 × Σ2 and AdS 4 × Σ3 solutions of N = 2, SO(4) gauged supergravity in seven dimensions with Σ2,3 being S 2,3 or H 2,3. The SO(4) gauged supergravity is obtained from coupling three vector multiplets to the pure N = 2, SU(2) gauged supergravity. With a topological mass term for the 3-form field, the SO(4) ∼ SU(2) × SU(2) gauged supergravity admits two supersymmetric...

Half-maximal gauged supergravity in seven dimensions coupled to n vector multiplets contains n + 3 vectors and 3n + 1 scalars parametrized by \( {\mathbb{R}}^{+}\times \mathrm{SO}\left(3,\mathrm{n}\right)/\mathrm{SO}(3)\times \mathrm{SO}\left(\mathrm{n}\right) \) coset manifold. The two-form field in the gravity multiplet can be dualized to a three-form field which admits a...

Through consistent Kaluza-Klein reduction, we construct 3D \( \mathcal{N}=2 \) gauged supergravities corresponding to twisted compactifications of M5-branes on a product of constant curvature Riemann surfaces, including Kähler-Einstein four-manifolds. We extend the reduction to fermionic supersymmetry variations in order to determine the 3D Killing spinor equations and classify...

We construct a consistent reduction ansatz of eleven-dimensional supergravity to N =2 SO(4) seven-dimensional gauged supergravity with topological mass term for the three-form field. The ansatz is obtained from a truncation of the S 4 reduction giving rise to the maximal N =4 SO(5) gauged supergravity. Therefore, the consistency is guaranteed by the consistency of the S 4...

We study N = 5 gauged supergravity in three dimensions with compact, non-compact and non-semisimple gauge groups. The theory under consideration is of Chern-Simons type with USp(4, k)/USp(4) × USp(k) scalar manifold. We classify possible semisimple gauge groups of the k = 2, 4 cases and identify some of their critical points. A number of supersymmetric AdS 3 critical points are...
