【报告摘要】：In this talk we will discuss high order methods for some classes of non-local equations. The equations that we are interested in include: time fractional differential equations, integro-differential equations with weakly singular kernels, time-space fractional equations, and so on. One of the main features of these equations is their non-locality, which makes the design of numerical methods difficult. We will present some efficient numerical methods specially adapted to these problems, including fast high order time stepping schemes with low storage for the time fractional differential equation, two kinds of spectral methods for the time-space fractional equation and integro-differential equations with weakly singular kernel. In particular, some new methods making use of Muntz polynomials, in both traditional and ANN frameworks, will be presented and analyzed for problems with solutions of low regularity.
