报告摘要:In this talk, we will talk about the transverse linear asymptotic stability of one-dimensional small-amplitude solitary waves of the gravity water-waves system. It is shown that the semigroup of the linearized operator about the solitary wave decays exponentially within a spectral subspace supplementary to the space generated by the spectral projection on continuous resonant modes. The key element of the proof is to establish suitable uniform resolvent estimates in the exponentially weighted energy space, for which we need to use different arguments depending on the size of transverse frequencies. As a corollary of our main result, we also get the spectral stability in the unweighted energy space. This is a joint work with Frédéric Rousset (Orsay, France).
