摘要
通过建立一类新的带权的泛函空间，证明了相应的Ｓｏｂｌｅｖ空间理论。
In this paper, Tricomi Equation is studied by means of a finite element method. Some characters about spaces w i,1 (Ω)(i=0,1,2) prove the convergence of the method and w 1,1 (Ω) norm error estimate of linear finite element solution in a convex polygon of r z plane z≥0.
