Abstract
The dynamical critical behaviour of the +/-J Ising spin glass is inves tigated at the damage-spreading threshold T-d. The dynamical critical exponent z is observed as z = 1.75+/-0.08 at T-d = 1.70 for d = 2 and z = 1.73+/-0.14 at T-d = 3.92 for d = 3. The fractal dimensions of the damage cluster are estimated as d(f) = 1.35+/-0.08 for the 2D Ising s pin glass and d(f) = 1.47+/-0.08 for the 3D system, which satisfy the equation d(f) = d - beta/nu within the error bar.
