1. Weyl anomaly and the C -function in λ -deformed CFTs / Sagkrioti, Eftychia ; Sfetsos, Konstantinos ; Siampos, Konstantinos
For a general λ -deformation of current algebra CFTs we compute the exact Weyl anomaly coefficient and the corresponding metric in the couplings space geometry. [...]

2. The exact C -function in integrable λ -deformed theories / Georgiou, George ; Panopoulos, Pantelis ; Sagkrioti, Eftychia ; Sfetsos, Konstantinos ; et al
By employing CFT techniques, we show how to compute in the context of λ -deformations of current algebras and coset CFTs the exact in the deformation parameters C -function for a wide class of integrable theories that interpolate between a UV and an IR point. [...]

3. RG flows for λ -deformed CFTs / Sagkrioti, E. ; Sfetsos, K. ; Siampos, K.
We study the renormalization group equations of the fully anisotropic λ -deformed CFTs involving the direct product of two current algebras at different levels k1,2 for general semi-simple groups. [...]
