We study the limiting behavior of the solution of u t −e 2 u xx +u 3 −u=0, a<x<b, with a Neumann boundary condition or an appropriate Dirichlet condition. The analysis is based on «energy methods». We assume that the initial data has a «transition layer structure», i.e., ue∼±1 except near finitely many transition points. We show that, in the limit as e→0, the solution maintains its transition layer structure, and the transition points move slower than any power of e
