Wednesday, 07 June 2017, 14:00 at MR14 Centre for Mathematical Sciences – I will discuss the possible existence of travelling wave solutions for discrete nonlinear Schrödinger equations on a grid. I will show the influence of the nonlinearity in this problem and give some partial results for the long time stability. This is a joint work with Dario Bambusi, Joackim Bernier, Benoît …
