简介:通过应用范数形式的锥拉伸与压缩不动点定理,一类含有一维P—Laplacian算子的奇异非线性四点边值问题的正解的存在性被考查,尽管非线性项含有未知函数的一阶导数。
简介:(连续)为电子结构的答案的计算的不同订单的有限元素近似在一些报纸被建议,这些途径的表演正在变得可估计并且现在很好被理解。在这份出版物,作者建议由联合有限元素网孔的精炼为完整潜力的电子结构计算扩大这discretization,在溶液随溶液主要是常规的区域的多项式近似的度的增加是很单个的的地方。近似性质的增加的这联合,做在一priori或一种posteriori方式,甚至当答案是单个的时,是著名的通常关于自由的度的数字生产最佳的指数的类型集中率。这里执行的分析在Hartree-Fock和Kohn假冒的问题的情况中支撑这个性质。
