 the optimal convergence
 Numerical results on a variety of problems, including a boundary-layer problem, and a nonlinear problem, verify the optimal convergence of the methods, even under more relaxed conditions than those assumed by theory. Convergence of the real space and reciprocal lattice sums in the Green's function is investigated and the optimal convergence parameter is chosen. Such identities were introduced by Bentkus [3] and applied (see Bentkus and Paulauskas [4]) to derive the optimal convergence rates in Chernoff-type lemmas and Euler's approximations of semigroups. In fact, the optimal convergence rate is attained in the extreme case when only one step of a quasi-Newton method is taken on this intermediate problem. The optimal convergence rate of the method is established in the broken $H^1$ energy and $L^2$-norms, and in particular, the convergence is uniform with respect to the Lamé parameter $\lambda$. 更多
 The optimal convergence concept for the interval iterative methods is analysed in the paper. The Krawczyk-Moore method has been shown to have the property of optimal convergence. A necessary condition for the convergence of Krawczyk interval methods is also given. 本文提出了区间迭代法的“最优”收敛性概念,对Krawczyk类区间迭代法的“最优”收敛性进行了分析,证明了Krawczyk—Moore算法是具有“最优”收敛性的区间迭代法。最后,还给出了一个关于Krawczyk类区间迭代法收敛的必要条件。 The discrete schemes based on the method of discrete operator for the first and third boundary value problems of the schistosomiasis model are proposed.The approximate solutions keep nonnegative and satisfy the maximum principle.The stability,convergence and error estimates of the method are discussed,and the optimal convergence rates in L2 and H1-are proved.The maximum norm estimate is given for the first boundary value problems. 对血吸虫病模型的第一和第三边值问题，应用离散算子法进行离散化，得到的数值解均恒为非负值且具有极大使原理．同时证明了Ｌ２模和Ｈ１模的最优误差估计，并对第一边值问题给出了最大模估计． Finite mixture models have wide applications in practice.

However, due to the irregularity of its parameter sauce, bony commonly ed statistical methods do not have theoretical backups in the finite future duel context. It regains unknown, for example, whether the maximum likelihoodestimetor of the mixing distribution achieves the optimal convergence rate n-1/4 which is already unusually low. In mis peper, we study a Class of restricted restricted maximum likelihood estimetors. It is shown that the estimator we propose achieves the optimal rate. In addition, we show that in the model where a structural parameter is involved, the convergence rate for estimetins the structural parameter is the usual n-1/2, not affected by the difficulties in estimetins the mixing distribution. Limiting distributions of some functionals of the rotried maximum likelitiwt estimetors are discussed.
