In this search, it has been studied the properties of the magnetoacoustic soliton
waves in ultra dense quantum plasma and its including ions and electrons and positrons
after taking quantum effects of electrons and positrons into consideration due
to their
Fermionic nature and the quantum diffraction, this is by the quantum Bom potential into
two momentum equations of electrons and positrons .
It has been studied the solitary waves of small amplitude by using reductive
perturbation method. The results have been compared to the solitary waves ones with what
others have reached in related references.
