N2 - The dynamics of one-dimensional solitons in attractive and repulsive Bose-Einstein condensates (BEC), loaded into an optical lattice with an external parabolic potential, was discussed. It was analyzed that in repulsive BEC, where the soliton was of the gap type, its effective mass was negative. The motion of the soliton in a long system was also discussed. A bright optical solution in a self-defocusing medium with a periodic structure of the refractive index was found to be stable in an anti-waveguide.
