Some puzzling problems in nonequilibrium field theories
arXiv:cond-mat/0210645
Abstract
I review some open problems on the ever-growing field of non-equilibrium phase transitions, paying special attention to the formulation of such problems in terms of Langevin equations or, equivalently, field-theoretical descriptions, and their solution using renormalization
