## Abstract We study global solutions of u~t~=ฮ__u__ + __f__(__u__, D__u__) with zero boundary data. Under suitable hypotheses on __f__, we show that an energy, which is roughly the __H__^1^ norm of __u__, cannot change too rapidly. When __f__ depends only on __u__, this estimate implies that all g
