Abstract
The evolution and collision of dark solitary waves (solitons) appearing in cigar-shaped Bose-Einstein condensates with repulsive atom-atom interaction are here considered using a Boussinesq-Korteweg-de Vries description. We p rovide theoretical predictions and computer experiment evidence about their phase shifts or change of trajectories, in the space-time plot, correspond ing upon collisions. Details are also given about a suggested experiment th at could assess their genuine solitonic nature.
