英文摘要	An efficient multigrid solver for the Oseen problems discretized by Marker and Cell (MAC) scheme on staggered grid is developed in this paper. Least squares commutator distributive Gauss-Seidel (LSC-DGS) relaxation is generalized and developed for Oseen problems. Residual overweighting technique is applied to further improve the performance of the solver and a defect correction method is suggested to improve the accuracy of the discretization. Some numerical results are presented to demonstrate the efficiency and robustness of the proposed solver.; NSF [DMS-1115961, DMS-1418732, DMS-1217142]; Department of Energy [DE-SC0006903]; China Scholarship Council (CSC); Applied Mathematics Program within the Department of Energy Office of Advanced Scientific Computing Research as part of the Collaboratory on Mathematics for Mesoscopic Modeling of Materials [DE-SC0009249]; SCI(E); 中国科学引文数据库(CSCD); ARTICLE; chenlong@math.uci.edu; xiaozhe.hu@tufts.edu; wangming.pku@gmail.com; xu@math.psu.edu; 2; 237-252; 8
