内容摘要:
In this talk, we firstly introduce several nonlocal nonlinear differential systems and the Adomian decomposition method (ADM in short). Next, we give a global convergence of the ADM algorithm by analysis of Gamma function and Adomian polynomials, and deduce computable expression of the asymptotic solution by numerical analysis. Thirdly, we discuss identification of order of the fractional derivative in the model by using one observation of the solution, and a uniqueness is proved based on the asymptotic solution, and several examples, including nonlinear epidemic system and Fisher equation, are presented. Finally, some remarks and conclusion are given for further work in biomedical sciences.
