Title: Multisolitons and their stability in 1-d cubic NLS.
Abstract: The aim of this talk is first to describe the multisoliton manifold for the 1-d cubic NLS flow, and then to consider their stability. This continues recent work, joint with Herbert Koch, on energy estimates for this and other related integrable evolutions.
