The purpose of this paper is concerned with developing new integrable Vakhnenko–Parkes equations with time-dependent coefficients. The author obtains multiple soliton solutions and multiple complex soliton solutions for the time-dependent equations.
The developed time-dependent models have been handled by using the Hirota’s direct method. The author also uses Hirota’s complex criteria for deriving multiple complex soliton solutions.
The developed integrable models exhibit complete integrability for any analytic time-dependent coefficient.
The paper presents an efficient algorithm for handling time-dependent integrable equations with time-dependent coefficients.
The author develops two Vakhnenko–Parkes equations with time-dependent coefficients. These models represent more specific data than the related equations with constant coefficients. The author showed that integrable equations with time-dependent coefficients give real and complex soliton solutions.
The work presents useful techniques for finding integrable equations with time-dependent coefficients.
The paper gives new integrable Vakhnenko–Parkes equations, which give a variety of multiple real and complex soliton solutions.
