New localized excitations in a (2+1)-dimensional generalized Nozhnik-Novikov-Veselov system

Using an extended homogeneous balance approach and a multilinear variable separation method, we obtain a new general variable separation excitation for the (2+1)-dimensional generalized Nozhnik-Novikov-Veselov(GNNV) system. Based on the derived solution, two new types of localized excitations, i.e., a bell-like loop soliton and a peak-like loop soliton, are constructed and some evolutional properties of these novel semifolded localized structures are briefly discussed.
