摘要：

We calculate the effective action for disordered elastic manifolds in the ground state (equilibrium) up to 3-loop order. This yields the renormalization-group beta-function to third order in epsilon = 4 - d, in an expansion in the dimension d around the upper critical dimension d = 4. The calculations are performed using exact RG, and several other techniques, which allow us to resolve consistently the problems associated with the cusp of the renormalized disorder.
