    A=B

    其中:
    Gamma函数
    超几何级数 ,这里面
      Pochhammer记号
     
    我觉得这个式子还算不坏。当然它无法与高斯的
     
    相提并论,不过在如今这个年代,过分美好的式子早就被写进公式集里几百年了……我忍不住要把它抖出来炫耀一下。
    关键在于这个等式有明确的几何意义。椭圆曲线有一个有理点,这个式子的左边是这个有理点的陈类在某个闭路上的积分,右边是这有理点与闭路的交叉数(所以是一个整数!)。本来我的打算是通过超几何级数的性质来研究椭圆曲线的有理点。可是后来发现我们关于超几何级数的知识并不像我当初想的那么多(简直是太少了!那帮搞分析的人是做什么吃的!)就这么一个式子,我翻遍了整个公式集也没有找到。
    啊啊,不过还算不坏吧。真的很不坏。
