这份报纸建议最少平方的 Galerkin 有限元素计划解决秒顺序夸张方程。集中分析证明方法与最佳的精确性产出近似答案在(L 2 ()) 2 吗??
This paper proposes the least-squares Galerkin finite dement scheme to solve secona-oraer hyperbolic equations. The convergence analysis shows that the method yields the approximate solutions with optimal accuracy in (L2 (Ω))2 × L2 (Ω) norms. Moreover, the method gets the approximate solutions with second-order accuracy in time increment. A numerical example testifies the efficiency of the novel scheme. Key words Convergence analysis, Galerkin finite element, hyperbolic equations, least-squares, nu- merical example.
