“…Recently Kalita and Deka (2013) [1] have investigated ion acoustic solitons in a weakly relavistic magnetised plasma based on initial steaming speeds in which the lower limit of the speed of light to characterise relativistic compressive solitons is predicted. Besides, Kalita and Choudhury (2013) [10] have also established the role of unidirected relativistic electrons with inertia in the formation of the weakly relativistic ion acoustic solitons in magnetised plasma. Both subsonic and supersonic compressive solitons are established.…”

The nonlinearity of dust-acoustic waves in a dusty plasma whose constituents are negatively charged dust, ions and electrons following Boltzmann distribution, is investigated by Sagdeev potential method. Existence of both subsonic and supersonic compressive solitons of interesting characters is established in this magnetized plasma model based on dust charge Zd (involved in f) and temperature ratio. The condition of the existence of solitons is ݇ ௭ ଶ ‫ܯ‬ ଶ < 1 + (1 − ݂)ߙ ݂ < 1 ‫ܯ‬ ଶ The amplitudes and depths of the potentials of subsonic and supersonic compressive solitons increase with the increase of dust charge Zd, but decrease with the increase of temperature ratio .

“…Very recently, Kalita & Deka (2013) have studied ion acoustic (IA) solitons in weakly relativistic plasmas based on initial streaming speeds characterizing relativistic compressive solitons in the lower limit of the speed of light (c). The role of unidirected relativistic electrons with inertia in the formation of weakly relativistic ion acoustic solitons in magnetized plasmas showing the existence of subsonic and supersonic compressive solitons has also been focused on by Kalita & Choudhury (2013). The effects of relativistic electron temperature on parametric instabilities for intense laser propagation in under-dense plasmas form the most recent investigation of a group of authors (Zhao et al 2014) in which the concept of stimulated Raman scattering and Brilliouin scattering are considered.…”

In this model of a dusty plasma, we have investigated dust acoustic waves consisting of electrons with weak relativistic effects, Cairns distributed cold ions and negatively charged mobile dust. Dust acoustic (DA) compressive and rarefactive solitons of various amplitudes are established. The parameter ${\it\beta}$ involved in Cairns distribution is related to the non-thermal parameter ${\it\alpha}$. However, the increase of ${\it\beta}$, which is independent of temperature, becomes instrumental for complete linear increase or decrease of the amplitudes of both the compressive and rarefactive relativistic solitons. Hence it is worthwhile to note that the increase of ${\it\beta}$ is solely due to the rest energy and not due to kinetic energy in this relativistic plasma. This is one of the most significant results of our investigation. Also, the flux of negative charges from the dust particles, together with the effect of the relativistic electrons, appears to balance the positive charges of Cairns distributed ions for nearly constant growth of amplitudes.
