Supergravity realisations of $\lambda$-models

Georgios Itsios, Giuseppe Casale

Type-II supergravity solutions can be constructed from multiple λ-deformed coset CFTs on SO(n+1)/SO(n) that include undeformed AdS factors.

Claims

C1strongest claim

We construct solutions of type-II supergravity based on multiple copies and/or mixings of λ-deformed coset CFTs on SO(n+1)_k/SO(n)_k, with n = 2, 3, 4. The resulting ten-dimensional geometries contain undeformed AdS factors, thereby allowing a connection between λ-deformations and the AdS/CFT correspondence.

C2weakest assumption

That the λ-deformed coset CFTs on the specified groups can be consistently combined or mixed and lifted to explicit ten-dimensional type-II supergravity solutions that satisfy all equations of motion while obeying the imposed reality conditions.

C3one line summary

Type-II supergravity solutions are built from λ-deformed coset models that contain undeformed AdS spaces, connecting these deformations to AdS/CFT while constraining λ via reality conditions.
