Weyl anomaly and the $C$-function in $\lambda$-deformed CFTs
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. By incorporating the exact β -function found in previous works we show that the Weyl anomaly is in fact the exact Zamolodchikov's C -f...
