Encyclopedia > Hilbert's seventh problem

Hilbert's seventh problem concerns the irrationality and transcendence of certain numbers (Irrationalität und Transzendenz bestimmter Zahlen). In its geometric formulation, it asks whether the following statement is provably true: In mathematics, an irrational number is any real number that is not a rational number, i. ... In mathematics, a transcendental number is any irrational number that is not an algebraic number, i. ... Geometry (from the Greek words Ge = earth and metro = measure) is the branch of mathematics first introduced by Theaetetus dealing with spatial relationships. ...

In an isosceles triangle, if the ratio of the base angle to the angle at the vertex is algebraic but not rational, then the ratio between base and side is always transcendental.

A special case of this problem asks: For alternate meanings, such as the musical instrument, see triangle (disambiguation). ... In mathematics, an algebraic number relative to a field F is any element x of a given field K containing F such that x is a solution of a polynomial equation of the form anxn + an−1xn−1 + ··· + a1x + a0 = 0 where n is a positive integer called the degree... In mathematics, an irrational number is any real number that is not a rational number, i. ... In mathematics, a transcendental number is any irrational number that is not an algebraic number, i. ...

Is ab transcendental, for algebraic a ≠ 0,1 and irrational algebraic b?

When b is rational, ab will be algebraic. In mathematics, a transcendental number is any irrational number that is not an algebraic number, i. ... In mathematics, an algebraic number relative to a field F is any element x of a given field K containing F such that x is a solution of a polynomial equation of the form anxn + an−1xn−1 + ··· + a1x + a0 = 0 where n is a positive integer called the degree... In mathematics, an irrational number is any real number that is not a rational number, i. ...


The special problem was solved by Aleksandr Gelfond in 1934, and refined by Theodor Schneider (1911 - ) in 1935. They proved that ab is transcendental when b is both algebraic and irrational. This result is known as Gelfond's theorem or the Gelfond-Schneider theorem. 1934 was a common year starting on Monday (link will take you to calendar). ... A database query syntax error has occurred. ... 1935 was a common year starting on Tuesday (link will take you to calendar). ... In mathematics, the Gelfond-Schneider theorem is the following statement, originally proved by Aleksandr Gelfond: If is an algebraic number (with and ), and is an irrational algebraic number, then is a transcendental number. ...


From the point of view of generalisations, this is the case

of the general linear form in logarithms.
