The development history of mathematics can be roughly divided into four periods. The first period is the formation period of mathematics, and the second period is the period when mathematics remains unchanged. Its research results include Lee's constant formula, Fahrenheit theorem, Su's cone and so on.

introduce

The Chinese nation is a nation with splendid culture and a long history. Among the splendid cultural treasures, mathematics also has many dazzling auras in the history of world mathematics development. Many research achievements of China's ancient arithmetic have given birth to advanced thinking methods of western mathematical design, and many world-leading mathematical research achievements in modern times are named after China mathematicians.

Lee's constant formula

Mathematician Li's research achievements in the summation of series are named Li's constant internationally.

Fahrenheit theorem

Fahrenheit theorem is the research result of Hua, a famous mathematician in China. Fahrenheit theorem is that a semi-automorphism of a body must be automorphism, automorphism or anti-isomorphism. Mathematician Hua's research results on complete triangular sum are called "Fahrenheit theorem" by the international mathematics community; In addition, he and mathematician Wang Yuan put forward the approximate calculation method of multiple integrals, which is internationally known as the "King of China Method".

Su's cone

Mathematician Su's research achievements in affine differential geometry are named "Su's cone" internationally. Academician Su's brilliant discovery in affine differential geometry is that he constructed an affine invariant quartic (third-order) algebraic cone for general surfaces. In affine surface theory, many covariant geometric objects, including two principal tangents, three Dabao tangents, three Segray tangents and affine normals, can be reflected by this cone and its three vertex lines in a wonderful way, forming a very attractive composition. This cone is called Su cone.
