Exact solutions for the ion sound Langmuir wave model by using two novel analytical methods

Results in Physics, 2020
In the present paper, the system of equations for the ion sound and Langmuir waves (SEISLWs) is considered to obtain the new solitary wave solutions of the non-linear evolution equations. Here, we used the relatively two new analytical methods to achieve

Some electrostatic structures of the mKP equation for a nonthermal plasma system by a unified solver technique

Journal of Taibah University for Science, 2023
The reductive perturbation technique is used to obtain the Modified KP equation at critical densities distinguished by the MKPE in plasma ion pair with fast electron positron. The new structures reveal that super-solitary and period waveforms are derived

Boussinesq’s equation for water waves: the soliton resolution conjecture for Sector IV

Advanced Nonlinear Studies
We consider the Boussinesq equation on the line for a broad class of Schwartz initial data relevant for water waves. In a recent work, we identified ten main sectors describing the asymptotic behavior of the solution, and for each of these sectors we ...
