<正> The nonlinear dust acoustic waves in two-dimensional dust plasma with dust charge variation is analyticallyinvestigated by using the formally variable separation approach. New analytical solutions for the governing equation ofthis system have been obtained for dust acoustic waves in a dust plasma for the first time. We derive exact analyticalexpressions for the general case of the nonlinear dust acoustic waves in two-dimensional dust plasma with dust changevariation.
