摘要
At the Second International Conference of Mathematics, Hilbert raised 23 problems, which promoted the development of mathematics in the 20th century. Among them, the 13th problem can be described as follows: Can the solution of any algebraic equation be expressed by superpositions of some functions of one variable? Hilbert conjectured that the solution of the equation x^7+ax^3 +bx^2+cx+1=0, viewed as a function of a, b, c,
