Abstract The lambda deformation of the pure spinor formalism of the superstring in the AdS 5 × S 5 background is introduced. It is shown that the deformation preserves the integrability as well
Generalized IIB supergravity from exceptional field theory

We discuss the perturbative stability of an AdS 3 non-supersymmetric solution of the type-IIB supergravity, whose internal geometry is given by the direct product of a round three-sphere and two
Target space supergeometry of η and λ-deformed strings

Integrability is believed to underlie the AdS3/CFT2 correspondence with sixteen supercharges. We elucidate the role of massless modes within this integrable framework. Firstly, we find the dressing
Classical and quantum aspects of Yang-Baxter Wess-Zumino models

A bstractWe investigate the integrable Yang-Baxter deformation of the 2d Principal Chiral Model with a Wess-Zumino term. For arbitrary groups, the one-loop β-functions are calculated and display a
Analytic integrability for strings on η and λ deformed backgrounds

We consider dynamics of scalar and vector fields on gravitational backgrounds of the Wess–Zumino–Witten models. For SO(4) and its cosets, we demonstrate full separation of variables for all fields
Integrable asymmetric λ-deformations
