Sun Zhiwei

Sun Zhiwei (zh-cpw|c=孙智伟|p=Sūn Zhìwěi|w=Sun Chihwei, b. October 16, 1965) is a Chinese mathematician, working primarily on number theory, combinatorics, and group theory.

Born in Huai'an, Jiangsu, Sun and his twin brother Sun Zhihong proved a theorem about what are now known as the Wall-Sun-Sun primes that guided the search for counterexamples to Fermat's last theorem.

In 2003, he presented a unified approach to three famous topics of Paul Erdős in combinatorial number theory: covering systems, restricted sumsets, and zero-sum problems or EGZ Theorem.

He used q-series to prove that any natural number can be represented as a sum of an even square and two triangular numbers. Recently, he has claimed to prove that any natural number can be represented as a sum of a square and an odd square and a triangular number.

His Erdős number is 2. And he is the Editor-in-Chief of [http://ijmm.dixiewpublishing.com International Journal of Modern Mathematics] .
