摘要：

The usual linear renormalization group (LRG) used in pin glasses is studied when a small nonlinear term is introduced in the relationship between block-spin variables. Contrary to what happens in uniform systems, this perturbation gives a singular contribution to the fixed-point Hamiltonian within the approximations used. It is then claimed that the LRG is inappropriate for spin glass systems.
