本文试图从新的角度研究质数的充分条件，给出两个新的三角和公式，明确了计算出S集（特征和）的方法，计算出了前所未知的S集列表，以多项式的形式描述了质数新的必要条件，并进行了初步的验证，期待着能够被进一步加以证明。本文所得出的初步结果，将导致一种全新的数学研究方法的产生，并指向了数学难题NP完全问题的解决路径。
本文通过研究和分析已经获知的质数的S集（特征和），发现其中任意一位的符号Sj都是有规律可寻的，首次系统地揭示出确定S集中符号规律的法则，将会推动数论中特征和、三角和理论的发展。探讨了更加便于应用的新类型的质数充分必要条件，只需要较小的计算量就可以进行大质数识别的多项式公式，给出了数学难题“NP完全问题”的解决路径。在经典的数论中，主要是偏重于对“数”的研究。而在本文中，是把数字的结构分解成由若干位...

We show that a homology plane of general type has at worst a single cyclic quotient singular point. An example of such a surface with a singular point does exist [MS, Theorem 3.1]. We
also show that ...
