Abstract
The integrability via Painlevé analysis as well as conservation laws is established for a new type of generalized NLS equation in 2+1 dimensions. By adapting ZS-AKNS' spectral problem to the system, we study a new breed of solitons, corresponding to the discrete spectral parameters that depend on both time and space. Explicit single and double solitons are also given.
