Description
The critical behavior of a quenched random hypercubic sample of linear size L is considered, within the 'random-Tc' field theoretical model and the mean-field approximation. A finite-size scaling behavior is established and analyzed and the problem of self-averaging is clarified for different critical regimes. (author)
