A Second-order Two-scale FEM for Time-fractional Diffusion Equation with Small Rough Periodic Coefficients
摘要
Abstract
In this paper, a second-order two-scale(SOTS) asymptotic expansion for time-fractional dif-fusion equation with rough periodic coefficients is presented .Based on the SOTS ’ s asymptotic expansion , the SOTS’ s computational method is constructed .Numerical experiments are carried out to show that the SOTS’ s computational method is effective .关键词
