摘　　要：用ＣＲＯＵＺＥＩＸ－ＲＡＶＩＡＲＴ元解非自共轭椭圆型问题的重叠型区域分解算法顾金生（北京航空航天大学动力系）胡显承（清华大学应用数学系）ＯＶＥＲＬＡＰＰＩＮＧＤＯＭＡＩＮＤＥＣＯＭＰＯＳＩＴＩＯＮＭＥＴＨＯＤＦＯＲＮＯＮＳＥＬＦＡＤＪＯＩＮＴＥＬＬＩ...AbstractWith the discrete maximum principle constructed in this paper,we show the geometric convergence of the parallel Schwarz alternating method for the numerical solutions of second order nonselfadjoint elliptic problems discretized by the piecewise linear nonconforming finite elements. The relation between its contrergence factor and the subdomain division is also given.
