# Sun Zhiwei

Sun Zhiwei ( pinyin: Sūn Zhìwěi; Wade-Giles: 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.[1]

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

His Erdős number is 2. And he is the Editor-in-Chief of International Journal of Modern Mathematics.
