本文研究一类一维抛物型方程初边值问题半离散有限元解 .对 iku-uh 分别得到函数及导数O(hk+ 2 .5 )阶及 O(hk+ 2 )
In this paper,we study the semidiscrete in space Galerkin method for a class of parabolic initial boundry value problems in one dimensional case.we obtain ultra approximation between i ku and u h of O(h k+2.5 ) and O(h k+2 ) order for function and derivative,respectively.
