Sun Zhiwei (zh-cpw|c=孙智伟|p=Sūn Zhìwěi|w=Sun Chihwei, b.
October 16 ,1965 ) is a Chinesemathematician , working primarily onnumber theory ,combinatorics , andgroup theory .Born in Huai'an, Jiangsu, Sun and his twin brother
Sun Zhihong proved a theorem about what are now known as theWall-Sun-Sun prime s that guided the search for counterexamples toFermat's last theorem .In
2003 , he presented a unified approach to three famous topics ofPaul Erdős in combinatorial number theory:covering system s,restricted sumset s, andzero-sum problem s orEGZ Theorem .

q-series to prove that any natural number can be represented as a sum of an even square and twotriangular number s. 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
