     a set of multi-fluid equations and maxwell’s equations are carried out to investigate the properties of nonlinear fast magnetoacoustic solitary waves with the combined effects of dusty plasma pressure and transverse perturbation in the bounded cylindrical geometry. the reductive perturbation method has been applied to the dynamical system causeway and the derived two dimensional cylindrical kadomtsev–petviashvili equation (ckp) predicts different natures of solitons in complex plasma. under a suitable coordinate transformation the ckp equation can be solved analytically. the change in the soliton structure due to mass of dust, ion temperature, ion density, and dust temperature is studied by numerical calculation of the ckp equation. it is noted that the dust cylindrical fast magnetoacoustic solitary waves in warm plasmas may disappear slowly because of an increase in dust mass. the present analysis could be helpful for understanding the nonlinear ion-acoustic solitary waves propagating in interstellar medium and pulsar wind,which contain an excess of superthermal particles.
