Dissipative and higher order nonlinearity terms are the perturbation terms taken into account. The integration is performed using the solitary wave ansatz, generating precise topological and non-topological soliton solutions. The existence of the exact solutions is subject to parametric constraints.enProf. Dr. Sarfraz AhmadMATHEMATICSNon-Linear ModelsThesis
