A splitting technique for superposition type solutions of cubic nonlinear ordinary differential equations

, 2017
This paper deals with finding new solutions of nonlinear ordinary differential equations with cubic nonlinearity. Few theorems comprising existence of superposition of two Jacobian elliptic functions as its solutions have been proved.

Variational theory of solitons for a higher order generalized Camassa-Holm equation

, 2017
In this paper we show the existence of travelling wave solutions for a higher order generalized Cammasa-Holm type equation. We follow a variational approach by characterizing travelling waves as critical points of a suitable functional.

Stability and Unstability of the Standing Wave to Euler Equations

, 2017
In this paper, we first discuss the well-posedness of linearizing equations, and then study the stability and unstability of the 3-D compressible Euler Equation, by analysing the existence of saddle point.

Existence of periodic traveling waves for the rotation-Kadomtsev-Petviashvili equation

, 2016
In this paper, via a variational approach, we study the existence of periodic traveling waves for the rotation Kadomtsev-Petviashvili equation. We show that those periodic solutions are characterized as critical points of some functional, for which the ...

Extremes in Branching Random Walk and Branching Brownian Motion

, 2013
Branching random walk (BRW) and branching Brownian motion (BBM) are mathematical models for population growth and spatial displacement. When resources are plentiful, population sizes grow exponentially in time.
