简介:让是四元数海森堡组,并且让P是仿射的自守组。我们上经由P的单一的代表在四元数海森堡组上开发连续小浪变换的理论。光线的小浪的一个班被构造。反的小浪变换被使用光线的小浪简化。然后,我们上调查氡变换。一个Semyanistyi-Lizorkin空格被介绍,在哪个上氡变换是bijection。我们由欧几里德几何学的Fourier变换和组Fourier变换在两个上处理氡变换。这二个处理是实质上相等的。如果小浪是光滑的,我们也由使用小浪给一个倒置公式,它不要求功能的光滑。另外,我们获得上与亚拉普拉斯算符联系的氡变换的一个倒置公式。

简介:就制造者在无常下面冒险心理因素和信息歧义的决定而言,新奇TOPSIS基于前景理论(磅)和trapezoidalintuitionistic,为组决策的模糊数字(TrIFNs)被调查,在哪个标准价值和标准重量拿TrIFNs的形式,并且决定制造者的重量是未知的。第一,为TrIFNs的距离措施被用来在trapezoidalintuitionistic下面导致值功能模糊环境。第二,距离措施的概念和trapezoidalintuitionistic模糊加权的平均操作员被采用导致决定制造者的重量,因此,决定制造者选择能被聚集。然后,基于磅的分离措施和相对亲密系数被定义并且为在trapezoidalintuitionistic下面评价选择的一个算法模糊环境被建议。最后,一个数字例子进一步说明建议TOPSIS方法的实物和有效性。
