报告题目：Compact and linear         method for the generalized diffusion equation

报告摘要：The generalized diffusion equation with a delay has inherent complex nature because its analytical solutions are hard to obtain. Therefore, one has to seek numerical methods, especially the high-order accurate ones, for their approximate solutions. In this talk, we have established the results of the numerical asymptotic stability of the compact and linear         method for the two classes of generalized delay diffusion equation. The convergent results in the maximum norm are studied according to the consistency analysis and Lax theorem. In the end, a series of numerical tests on stability and convergence are carried out to support our theoretical results.
