Compacton and foldon excitations in the generalized (2+1)-dimensional Nizhnik-Novikov-Veselov equation

Using the variable separation approach, abundant localized coherent solutions are obtained for the generalized (2+1)-dimensional Nizhnik-Novikov-Veselov (GNNV) equation. Two special types of localized excitations, compactons and foldons, are discussed. The behavior of the interactions for three-compacton solutions and two foldon solutions are investigated, and many interesting interaction properties are revealed.
