In particular, using the \"energy approach\" proposed by Bronsard and Kohn [5], if $\\varepsilon\\ll 1$ is the diffusion coefficient, we show that in a time scale of order $\\varepsilon^{-k}$ nothing happens and the solutions maintain the same number of transitions of its initial datum $u_0$. The novelty of our result consists mainly in the role of the initial velocity $u_1$, which may create or eliminate transitions in later times. Numerical experiments are also provided in the particular case of the Allen-Cahn equation with relaxation.", "revisions": [ { "version": "v1", "updated": "2015-10-24T17:36:53.000Z" } ], "analyses": { "keywords": [ "allen-cahn equation", "hyperbolic variation", "space dimension", "slow motion", "initial datum" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
