LONDON, May 14 call (Reporter Huang Kun) Goldbach conjecture in mathematics on the crown jewel, and it has a called a “weak Goldbach conjecture sister version. “Nature” magazine Web site reported that on the 14th, the Chinese mathematician Tao Zhexuan “weak Goldbach conjecture”, a breakthrough is expected to eventually solve the problem of this century.
1742, Goldbach in a letter addressed to another mathematician Leonhard Euler, a mathematical conjecture, this conjecture can be used mathematical language statements as follows: any more than 5 The integer can be written as the sum of three primes. Euler’s another equivalent version in the reply, or any even number greater than 2 can be written as two prime numbers, such as 8 = 5 +3. Today’s common “Goldbach conjecture,” the statement of the latter, it is also called “strong Goldbach conjecture” or even Goldbach Conjecture. Can be launched from this conjecture: any odd number greater than 5 can be written in three prime numbers, that is, the so-called “weak Goldbach conjecture.
According to Nature magazine, the Chinese mathematician of the University of California, the Tao Zhexuan in the proof of “weak Goldbach conjecture” made a breakthrough, he proved in a paper, you can odd written five prime numbers.
the this paper has been submitted to academic journals, in among the reviewers process.
id=”content”> “natural” quoted Tao Zhexuan saying that the expected number of primes required to three, thus proving the “weak Goldbach conjecture. He also said that the weak Goldbach conjecture “and” strong Goldbach conjecture or much easier to prove the strong Goldbach conjecture, mathematicians are still facing great difficulties compared.
Born Australia Tao Zhexuan, is now the University of California at Los Angeles professor of mathematics. He grew up like math, 21 years old, received his Ph.D. at Princeton University, 24-year-old University of California, Los Angeles, hired as a full professor. In 2006, the 31-year-old he won the highest honor of the international mathematical community, “Fields Medal”.
