Abstract

The properties of random fixed points for systems in the directed percolation universality class were discussed. For strong enough disorder the critical behavior was found to be controlled by a strong disorder fixed point which was isomorph with the fixed point of random quantum Ising systems. It was observed that, in the fixed point dynamical correlations are logarithmically slow and the static critical exponents are conjecturedly exact for one-dimensional systems. According to the renormalization group analysis, for models in the parity conserving universality class there is no strong disorder fixed point.
