Significantly, it is shown that the proposed systemserves as an integrable (3 + 1)-dimensional generalization of the well-studied (2 + 1)-dimensional dispersionless Davey–Stewartson system. This way, an interesting newexample on integrability in higher dimensions is presented, with potential applicationsin analyzing three-dimensional nonlinear waves across various fields, includingoceanography, fluid dynamics, plasma physics, and nonlinear optics. Importantly, theintegrable nature of the system suggests that established techniques like the study ofsymmetries, conservation laws, and Hamiltonian structures could be applicable.
