**Abstract:**

Chunxuan Jiang is a controversial mathematician in the history of modern mathematics. In China Jiang’s work was completely repelled and been considered as pseudoscience. Jiang dedicates his work to Alma Mater (Beihang University) and China which rejected. Below are some achievements claimed by Jiang himself, which has not been acknowledged. Jiang took great interest in number theory and has been dedicated to the study of it in his spare time since 1973. He paid much attention to communicate with mathematicians both home and abroad. Through his 30 years’ hard work, he achieved remarkable achievements in number theory, successfully solving several well-acknowledged tough mathematical problems using new mathematical methods: (1) Extended trigonometric function to prove the Fermat's Last Theorem; (2) Finding the Jiang’s function Jn(ω) which reveals the nature of distribution of the prime number, thus proving the Goldbach Conjecture; (3) Denied the Riemann hypothesis; (4) developed the Isonumber theory and established mathematic system of Isonumber.
