Description
In this work we study the complexity growth in the anisotropic Einstein-Axion-Dilaton Gravity using ”complexity = action” (CA) and ”complexity = volume” (CV)conjectures. We compute analytically the complexity growth rate and we find that the Lloyd’s bound does not saturate in this model and difference between the complexity growth rate and the Lloyd’s bound is proportional to pressure difference in the longitudinal and transverse directions. And also one can see that the Loyd’s bound is violated in large anisotropies. This violation is maybe connected to the violation of the Kovtun-Son-Starinets (KSS) bound on the shear viscosity to entropy density ratio in this model.
