Abstract
In this study, a (3+1)-dimensional modified Kadomtsev–Petviashvili system with variable-coefficients (vcmKP) arising in many fields of science like plasma physics, optics, and fluid mechanics is studied. The consistent Riccati expansion solvability technique is applied to the vcmKP system to obtain necessary integrability conditions between the variable coefficients. Moreover, many novel different types of travelling wave solutions are given. Additionally, the vcmKP system is reduced to a nonlinear third order ordinary differential equation and many other new solutions are obtained. Finally, some plots are given to illustrate how the arbitrary function choices affect the propagation of the wave solutions.
