报告内容:

We investigate the focusing NLS(n,n) equation   and find its multi-hump compactons for n>1, whose properties are analyzed   in detail. Particularly, we find that the maximal intensities of the   multi-hump compactons approach to the natural base e as n 1+ . Moreover,   we numerically study the stabilities and interactions of the single-hump and   double-hump compactons such that some stable multi-hump compactons and   elastic interactions are found for some small values of the parameter n.
