简介：在这篇论文，我们在R~d在一些non-tensorproduct领域上建议著名Fourier方法，包括单一、所谓超级单一它由组成(d+1)!笨人lices。作为二个例子，在2-D和3-D大小写一超级单一分别地作为平行等边六角形和平行四边的十二面体被显示出。我们扩大了大多数概念和传统的Fourier方法的结果在上多变量盒子例如Fourier基础系统，傅里叶级数，分离Fourier变换(DFT)和它的快算法(快速傅里叶变换)在上超级单一，以及概括正弦和余弦变换(DST，DCT)并且相关快算法在上一单一。在在这些域上的一个像拉普拉斯算符的操作符的基本直角的系统和特徵函数之间的Therelationship被探索。

简介：在这份报纸，我们建议二新不安单一的变体。没有介绍人工的变量，解决线性编程问题，二的各个使用双枢规则完成最初的可行性，然后最初的枢规则完成optimality。第二个算法，修正第一，被设计更高效地处理高度退化的问题。有关不安的优点的一些有趣的结果被建立。从初步的测试的数字结果也被报导。[从作者抽象]

简介：在这笔记，我们学习多变量伯恩斯坦多项式B的本地行为，在d维的单一的SRd上。当n趋于到无穷，为同意足够的高顺序的衍生物进入x的功能f，我们导出Bnf的完全的asymptotic扩大。n1的所有系数仅仅取决于f和x明确地被计算。结果组合的数字起一个重要作用。同等结果以一个方法由于R.张概括最近的公式。
