Stability of Periodic Traveling Wave Solutions to the Kawahara Equation
We analyse the stability of periodic, travelling-wave solutions to the Kawahara equation and some of its generalizations. We determine the parameter regime for which these solutions can exhibit resonance. By examining perturbations of small-amplitude solutions, we show that generalised resonance is a mechanism for high-frequency instabilities.

Elastic and nonelastic interactional solutions for the (2 + 1)-dimensional Ito equation
In this paper, based on the bilinear form and two new test functions, for the (2 + 1)-dimensional Ito equation, we obtain non-elastic interactional solutions composed of three different types of waves including the solitary wave, the periodic wave and ...

Nonlinear wave equations: constraints on periods and exponential bounds for periodic solutions
The authors discuss properties of the nonlinear wave equation \(\partial^2_t\varphi= \Delta\varphi+ f(\varphi)\), where \(f\in C^3(\mathbb{R},\mathbb{R})\) satisfies \(f(0)= 0\), while \(t\in (-\infty,+\infty)\) and \(x\in\mathbb{R}^N\). Solutions \(\varphi(x, t)\) are supposed to be periodic in \(t\), and for fixed \(t\) in \(L^2(\mathbb{R}^N)\) with ...

Exact solitary and periodic-wave solutions of the K(2,2) equation (defocusing branch)
An auxiliary elliptic equation method is presented for constructing exact solitary and periodic travelling-wave solutions of the K(2, 2) equation (defocusing branch). Some known results in the literature are recovered more efficiently, and some new exact

Collocation schemes for periodic solutions of neutral delay differential equations
We introduce two collocation schemes for the computation of periodic solutions of neutral delay differential equations (NDDEs): one based on a direct discretisation of the underlying NDDE, and one based on a discretisation of a related delay differential
