Abstract

By means of the multilinear variable separation(MLVS)approach,new interaction solutions with low-dimensional arbitrary functions of the(2+1)-dimensional Nizhnik-Novikov-Veselov-type system are constructed.Four-dromion structure,ring-parabolic soliton structure and corresponding fusion phenomena for the physical quantity U=λ(lnf)xy are revealed for the first time.This MLVS approach can also be used to deal with the(2+1)-dimensional Sasa-Satsuma system.
