On Transformations of the Rabelo Equations [PDF]
We study four distinct second-order nonlinear equations of Rabelo which describe pseudospherical surfaces. By transforming these equations to the constant-characteristic form we relate them to some well-studied integrable equations.

The (3 + 1)-dimensional variable-coefficient B-type Kadomtsev-Petviashvili equation is studied by using the Hirota bilinear method and the graphical representations of the solutions.

In this article, we apply a direct influential approach namely enhanced modified simple equation (EMSE) method to integrate the Burgers–Huxley (BH) and FitzHugh–Nagumo (FHN) equations which explain nerve pulse propagation in nerve fibers, circuit theory ...

In this paper, we propose a new fractional sub-equation method for finding exact solutions of fractional partial differential equations (FPDEs) in the sense of modified Riemann-Liouville derivative, which is the fractional version of the known (G′/G ...

Controlling the dynamics of Burgers equation with a high‐order nonlinearity
We investigate analytically as well as numerically Burgers equation with a high‐order nonlinearity (i.e., ut = νuxx − unux + mu + h(x)). We show existence of an absorbing ball in L2[0, 1] and uniqueness of steady state solutions for all integer n ≥ 1.

Higher-Order Rogue Wave and Rational Soliton Solutions of Discrete Complex mKdV Equations
The generalised perturbation (n, N − n)-fold Darboux transformation is used to derive new higher-order rogue wave and rational soliton solutions of the discrete complex mKdV equations.

Riemann-Hilbert Approach and N-Soliton Solutions For Three-Component Coupled Hirota Equations
A Riemann-Hilbert problem is employed to study integrable three-component coupled Hirota (tcCH) equations. Thus, we investigate the spectral properties of tcCH equations with a 4× 4 Lax pair and derive a Riemann-Hilbert problem, the solution of which is ...

The generalized Burgers equation with and without a time delay
We consider the generalized Burgers equation with and without a time delay when the boundary conditions are periodic with period 2π. For the generalized Burgers equation without a time delay, that is, ut = vuxx − uux + u + h(x), 0 < x < 2π, t > 0, u(0, t) = u(2π, t), u(x, 0) = u0(x), a Lyapunov function method is used to show boundedness and uniqueness

Motion of Inextensible Quaternionic Curves and Modified Korteweg-de Vries Equation
Many curve evolutions have been determined which are integrable in recent times. The motion of curves can be defined by certain integrable equations including the modified Korteweg-de Vries.

Nonanalytic solutions of the KdV equation
We construct nonanalytic solutions to the initial value problem for the KdV equation with analytic initial data in both the periodic and the nonperiodic cases.
