【 摘 要 】

We make use of a coordinate-free approach to implement Vakhitov–Kolokolov criterion for stability analysis in order to study the effects of three-body atomic recombination and lattice potential on the matter–wave bright solitons formed in Bose–Einstein condensates. We analytically demonstrate thatthe critical number of atoms in a stable BEC soliton is just half the number of atoms in a marginally stable Townes-like soliton and
