We use a prolonged system to localize these symmetries and establish the associated one-parameter Lie transformation group. In this transformation group, we deliver new exact solution profiles via the combination of various simple (seed and tangent hyperbolic form) exact solution structures. In this manner, we acquire an infinite amount of exact solution forms methodically. Furthermore, we demonstrate that the model may be integrated in terms of consistent Riccati expansion. Using the Maple symbolic program, we derive the exact solution forms of solitary-wave and soliton-cnoidal interaction. Through 3D and 2D illustrations, we observe the dynamic analysis of the acquired solution forms.eninfo:eu-repo/semantics/closedAccessMultiple-soliton-solutionsHirotasBoussinesq(2+1)-dimensional chaffee-infante equationPainleve truncated exapansion approachDynamic analysisBacklund transformationsResidual symmetriesScience & technologyPhysical sciencesPhysics, multidisciplinaryPhysicsArticle001100735500001751110.1088/1572-9494/acf8b61572-9494
