For the dyn.mics of three-dimen.ion.l electron.positron.ion.plasmas, a fluid quan.um hydrodyn.mic model is proposed by con.iderin. lan.au quan.ization.effects in.den.e ***–n.utral collision. in.the presen.e of the Coriolis force are also con.idered. The application.of the reductive perturbation.techn.que produces a wave evolution.equation.represen.ed by a damped Korteweg–de Vries equation. This equation. however, is in.ufficien. for describin. waves in.our system at very low dispersion.coefficien.s. As a result, we con.idered the highest-order perturbation. which resulted in.the damped Kawahara equation. The effects of the magn.tic field, lan.au quan.ization. the ratio of positron.den.ity to electron.den.ity, the ratio of positron.den.ity to ion.den.ity, an. the direction.cosin. on.lin.ar dispersion.laws as well as soliton.an. con.idal solution. of the damped Kawahara equation.are explored. The un.erstan.in. from this research can.con.ribute to the broader field of astrophysics an. aid in.the in.erpretation.of observation.l data from white dwarfs.
