首先给出了发展型非线性对流扩散方程的非协调EQ1^rot元的最优ε一致收敛性结果,并且根据Bram-ble-Hilbert引理得到了高精度的积分恒等式;最后得到了新的渐近展开式.
This paper presents a work on ε uniform convergence for nonconforming finite element EQEQ1^rot for the time-dependent nonlinear advection-diffusion equations. Moreover, two new integral identities are obtained by using of Bramble-Hilbert lemma. A new asymptotic expansion is also derived.
