Integrable $\lambda$-deformed $\sigma$-models are characterized by an underlying current algebra/coset model CFT deformed, at the infinitesimal level, current/parafermion bilinears. We promote deformation parameters to dynamical functions of time introduced as extra coordinate. It is conceivable that appropriately constraining them, beta-functions vanish and consequently $\sigma$-model stays co...

this study compared the use of five different models to describe the growth from birth to 20 weeks of age of kids from both genders of nondescript goats. fifty nine (59) nondescript kids were weighed weekly at the university of maiduguri livestock teaching and research farm, nigeria and the live weights were modeled. biologically relevant variables were estimated for each kid from the logistic,...

WZW models live on a moduli space parameterized by current-current deformations. The defines an ensemble of conformal field theories, which generically have $N$ abelian conserved currents and central charge $c > N$. We calculate the average partition function show that it can be interpreted as sum over 3-manifolds. This suggests ensemble-averaged theory has holographic dual, generalizing recent...
