Abstract
In this study, the closed-form wave solutions has been examined to the space–time fractional simplified Camassa-Holm equation through two potential techniques, namely the sine-Gordon expansion approach and the extended tanh function scheme. The equation explains the dispersion effects of several phenomena, including liquid drop patterning in plasma, fluid flow, fission and fusion processes, acoustics, control theory, etc. The fractional-order equation is transformed into a nonlinear equation through a complex transformation. Diverse solutions are determined, and for specified parametric values, the solutions are graphically assessed by depicting 3D and contour plots that provide kinks, singular kinks, plane-shaped, bell-shaped, and other types of solitons. All derived solutions are substituted into the original equation to ensure their accuracy, and the obtained solutions are compared with existing solutions in the literature to demonstrate their novelty. It is noteworthy that the suggested techniques are reliable, competent, and potential mathematical tools to establish closed-form wave solutions.
