Recently, the United States on the University of Chicago Conference on mathematical logic, gathered many mathematical logic from European and American experts and scholars, the General Assembly also invited 12 experts and scholars to make an academic report. Southern University of science and Technology College in 2008 Liu Jiayi as Asia University of college-level students only report one representative at the meeting for 40 minutes, his research in mathematical logic, experts give the young young man 22 years old from China cast eyes full of praise.

　　A paper raises international repercussions

　　In May this year, organized jointly by Beijing University, Nanjing University and Zhejiang Normal University logic Conference held in Zhejiang Normal University, Central South University junior scholar Liu Jiayi was invited to participate in this meeting, and made a present of reverse mathematics Ramsay (Ramsly) dye proof of the theorem on the strength of the second report. This is determined by the United Kingdom in mathematical logic, a guess the question Seetapun in the early 90 ‘s, more than 10 years, none of the many prominent researchers have been trying to solve. Liu Jiayi’s report to the outstanding open problem a negative answer, one’s words electrified his listeners.

　　June, mathematical logic international authority Magazine Journal of Symbolic Logic under Editor, and logic expert, and Chicago University Mathematics Department Denis Hirschfeldt Professor made to has papers review views, letter in the said, “I is past many research the problem and no fruit who one, see this a problem of eventually resolve was very happy, special as you to out of so beautiful of proved, please accept I on you of was praise of surprised of results of congratulates! ”

　　”Road brother” like psychology

　　Liu Jiayi real name Liu Lu, “Recalling” was his pen name.

　　Students eye in the of Liu Road is such of: high pick of was, a Vice glasses, a top baseball cap, back a double shoulder package, every day like work as, a early to library, sometimes may to to afternoon only came back; back came back a large heap English books, opened a this, full is English and symbol, although does not know Liu Jiayi see of is what book, but they clearly, this guy certainly will dry out doubled results. He will be playing the occasional game, but often hold those books see the night, until early this morning. Students ask his subjects, he will use a simple method to calculate or explained, in some cases, a formula can make it, the students said that he “cattle”, referred to him as “road brothers”.

　　Reserved and introverted, even shy Liu Road, it’s more like “Recalling” the name, he wished to be able to help bring fond memories of. He also enjoys physical, physical need to do a lot of testing, costs, not so much funding for a student, he likes psychology, has designed a set of cognitive psychology experiment. However, he is more interested in mathematical logic, he says to wait until he is 40 years old and later to do, before the age of 40 to attack math!
