Liu Lu

Liu Lu (born 2 April 1989) is a professor of mathematics at Central South University in Changsha, Hunan, where he is China's youngest full university Professor. As a 22-year-old undergraduate student Lu proved that Ramsey theorem for infinite graphs (the case n = 2) with 2-coloring does not imply WKL0 over RCA0, solving an open problem left by English logician David Seetapun in the 1990s. For this he was instantly promoted to full professor in the department where he was studying, and awarded a prize of 1 million renminbi. Some established professors were critical of his appointment voicing concern that he was too young, had no teaching experience and that the appointment was mostly designed to get media attention to Liu's university.
