Linear and nonlinear inertial Alfvén waves are studied in the presence of positively and negatively charged dust in electron-ion plasmas. The Sagdeev potential approach is employed to obtain solitary inertial Alfvén waves in such a multicomponent plasma. It is found that electron density dips are formed in the super Alfvénic region, which has behavior similar to the case of electron-ion plasmas. The amplitude of the electron density dip structure is decreased in the presence of positively charged dust particles, while it is increased due to negatively charged dust particles in dusty plasmas. The numerical results are shown for an illustrative purpose. The results can be applicable to explain some aspects of solar wind interactions with the comets and planets containing dusty plasma environments.
