Hy. Ruan, SIMILARITY REDUCTIONS OF NONLINEAR SCHRODINGER-EQUATION WITH PSEUDOPOTENTIALS, Communications in Theoretical Physics, 24(1), 1995, pp. 113-116
With the help of the nonlocal symmetry of the nonlinear Schrodinger eq
uation, we get two types of nontrivial new similarity reductions. A ty
pe of new exact solutions including the so-called interacting soliton
solution is also given.
