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. [...]

3. Flat holography and Carrollian fluids / Ciambelli, Luca ; Marteau, Charles ; Petkou, Anastasios ; Petropoulos, P. ; et al
We show that a holographic description of four-dimensional asymptotically locally flat spacetimes is reached smoothly from the zero-cosmological-constant limit of anti-de Sitter holography. [...]

4. 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. [...]
