报告题目:Finite element method for time fractional diffusion equations with constant time delay
摘 要:Finite element method is considered to solve time fractional diffusion equations with constant time delay. The regularity of solutions of these considered models is discussed, which exhibits multi-singularity in time. To overcome the multi-singularity, the symmetrical graded mesh is used to devise the fully discrete finite element scheme for the considered problems to achieve the global time optimal error estimate, while the uniform temporal mesh is employed to establish the fully discrete finite element scheme to obtain the local time error estimate. Besides, the stability of the above proposed numerical schemes is investigated in detail. Finally, some numerical tests are provided to verify the obtained theoretical results.
