题目::Time fractional equations

内容简介:This courses are concerned with numerical methods for solving time-fractional equations. The approach is based on some suitable time stepping schemes, of the type either convolution quadrature or finite difference. The main concern is on stability and error analysis of approximate solutions, efficient implementation and qualitative properties, under various regularity assumptions. The courses provide a comprehensive survey on the present ideas and methods of analysis, and it covers most important topics in this active area of research.
