报告题目:Asymptotic solutions and inverse order problems for several fractional-order epidemic systems based on non-Markovian process
报告摘要:This talk deals with numerical simulations and inverse order problems for several kinds of fractional-order epidemic systems based on non-Markovian process and asymptotic solution. The mathematical models are derived from statistical processes where the waiting time of a particle leaving a compartment follows power-law decay distribution. The asymptotic solution to a fractional-order epidemic model is derived by using the Adomian decomposition method, and numerical simulations are presented to reveal some dynamic behaviors of the system. Inverse problem of identifying the fractional order can be transformed to a nonlinear equation based on the asymptotic solution, and the uniqueness is proved under suitable conditions.
