Research Abstract

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.
