SINGULARITY STRUCTURE-ANALYSIS AND BILINEAR FORM OF A (2+1) DIMENSIONAL NONLINEAR SCHRODINGER (NLS) EQUATION

The integrable (2+1) dimensional generalization of the non-linear Schrodinger (NLS) equation discussed recently by Strachan is shown to admit the Painleve property. Further, we construct its bilinear form directly from the P-analysis which can then be used to generate its soliton solutions. We also indicate the absence of two genuine non-parallel ghost solitons which in isolation can produce a vanishing physical field in order to give rise to a 'dromion'.
