Lie symmetry analysis and explicit solutions of the time fractional fifth-order KdV equation. [PDF]
In this paper, using the Lie group analysis method, we study the invariance properties of the time fractional fifth-order KdV equation. A systematic research to derive Lie point symmetries to time fractional fifth-order KdV equation is performed.

A polynomial conjecture connected with rogue waves in the KdV equation
A polynomial conjecture, associated with rational solutions including rogue wave solutions of the KdV equation, is presented. The conjecture can be used to show that for the bilinear KdV equation, an arbitrary linear combination of two Wronskian ...

On rational similarity solutions of $KdV$ and $m$-$KdV$ equations [PDF]
This note presents rational similarity solutions \(u_ n\) in series for the KdV equation and \(v_ n\) for the modified-KdV equation. These solutions were expressed in terms of polynomials originally introduced by Yablonskij (1959) and Vorobiev (1965) to describe rational solutions of the second Painlevé equation.

New lower bounds on the radius of spatial analyticity for the KdV equation [PDF]
The radius of spatial analyticity for solutions of the KdV equation is studied. It is shown that the analyticity radius does not decay faster than $t^{-1/4}$ as time $t$ goes to infinity.

New solitary wave solutions for the Korteweg-de Vries (KdV) equation by a new version of the trial equation method are attained. Proper transformation reduces the Korteweg-de Vries (KdV) equation to a quadratic ordinary differential equation that is ...
