  • 简介:上个学期的一门课,我被分到了一组被称为“亚洲小旋风”的队伍里,原因是我们六个组员全是亚洲人。六个人中除了我,有一个控制欲极强的中国女孩,一个谨言慎行的日本男生,一个漂亮的泰国女土豪,一个自负的马来西亚女“夜叉”和一个神经兮兮的大龄印度男。

  • 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。
