Abstract
In this paper we prove an asymptotic estimate, up to the second-order included, on the behaviour of the onedimensional Allen-Cahn's action functionals, around a periodic function with bounded variation and taking values in ±1. The leading term of this estimate justifies and confirms, from a variational point of view, the results of Fusco-Hale [Dyn. Diff. Equation 1 (1989), 75-94] and Carr-Pego [Comm. Pure Appl. Math. 42 (1989), 523-576] on the exponentially slow motion of metastable patterns coexisting at the transition temperature.File in questo prodotto:
