Existence of Generalized Solitary Wave Solutions of the Coupled KdV–CKdV System
Qualitative Theory of Dynamical Systems, 2022The paper under review studies the existence of generalized solitary wave solutions to the following coupled KdV-CKdV system \[ \begin{cases} u_t+2bu_\xi+au_{\xi\xi\xi}=-2b(uv)_\xi,\\ v_t+bv_\xi+bvv_\xi+cv_{\xi\xi\xi}=-b(|u|^2)_\xi, \end{cases}\tag{1} \] where \(a,b,c\in\mathbb R\) are constants.

(1+1)-dimensional m-cKdV, g-cKdV integrable systems, and (2+1)-dimensional m-cKdV hierarchy
Canadian Journal of Physics, 2008A few isospectral problems are introduced by referring to that of the cKdV equation hierarchy, for which two types of integrable systems called the (1 + 1)-dimensional m-cKdV hierarchy and the g-cKdV hierarchy are generated, respectively, whose Hamiltonian structures are also discussed by employing a linear functional and the quadratic-form identity ...

Nonlocal Symmetry, Painlevé Integrable and Interaction Solutions for CKdV Equations
Symmetry, 2021 In this paper, we provide a method to construct nonlocal symmetry of nonlinear partial differential equation (PDE), and apply it to the CKdV (CKdV) equations.

Nonlinear concentric water waves of moderate amplitude
Wave MotionWe consider the outward-propagating nonlinear concentric water waves within the scope of the 2D Boussinesq system. The problem is axisymmetric, and we derive the slow radius versions of the cylindrical Korteweg - de Vries (cKdV) and extended cKdV (ecKdV)
