Lecturer: Wu Guocheng

Abstract:

After review of the definition of classical Riemann-Liouville derivative, the delta differential equation method covering several common fractional integral forms is proposed to define the generalized fractional integral in combination withn-fold integral. Through the boundedness theorem of a fractional integral, the mathematical constraints of a generalized kernel function are given; According to the classical random walk theory, the report provides the physical explanation of a generalized fractional derivative. At the end of the report, the prediction and correction algorithm of fractional differential equations is studied, the convergence and convergence order of the numerical format when the fractional order is 2 to 3 are discussed, and the rationality of the definition of generalized fractional derivative and the feasibility of numerical calculation are explained.
