New exact solutions and complex wave excitations in (2+1)-dimensional generalized Nozhnik-Novikov-Veselov system
(2+1)维广义 Nizhnik-Novikov-Veselov 系统的新严格解和复合波激发

Starting from an extended mapping approach and a linear variable separation method, new families of exact solutions with arbitrary functions for (2+1)-dimensional Generalized Nozhnik-Nivikov-Veselov system(GNNV) are derived. We found that some new and interesting complex wave excitations are derived from a periodic wave solution.
