Currently, it is impossible for us to discuss the World without trgonometric functions. Abelian functions are advanced functions that highly generalizes the trigonomatric functions, and will be, no doubt, very important functions in the future. Any Abelian function has a number that called "genus". Trigonometric functions are of genus 0 and elliptic functions are of genus 1. Athough these functions have very concrete theory, Abelian functions of genus greater than 1 has so poor in concrete theory. Through this project I constructed a very concrete theory of Abelian functions of genus greater than 1.

目前，我们不可能在没有三角函数的情况下讨论世界。阿贝尔函数是高度概括三角函数的高级函数，毫无疑问将是未来非常重要的函数。任何阿贝尔函数都有一个称为“属”的数字。三角函数属于0型，椭圆函数属于1型。虽然这些函数有非常具体的理论，但大于1的阿贝尔函数的具体理论却很差。通过这个项目，我构建了一个非常具体的大于 1 的属的阿贝尔函数理论。
