摘要：
Damage spreading in the 2D and 3D Heisenberg model is considered. For the 3D model, there is a critical temperature T1 = 1.15 between a frozen phase and a chaotic phase at low temperature. There is another critical temperature T2 approximately 0.3 below which the final damage depends on its initial value. For the 2D case, there is a transition at T0 approximately 0.5 between a frozen phase and a low-temperature chaotic phase which might be characterized by the existence of infinite critical points.
