  2. Hilbert's problems - Wikipedia

    en.wikipedia.org/wiki/Hilbert's_problems

    The following are the headers for Hilbert's 23 problems as they appeared in the 1902 translation in the Bulletin of the American Mathematical Society. [1] 1. Cantor's problem of the cardinal number of the continuum. 2. The compatibility of the arithmetical axioms. 3. The equality of the volumes of two tetrahedra of equal bases and equal altitudes.

  3. Hilbert's seventeenth problem - Wikipedia

    en.wikipedia.org/wiki/Hilbert's_seventeenth_problem

    Hilbert's seventeenth problem. Hilbert's seventeenth problem is one of the 23 Hilbert problems set out in a celebrated list compiled in 1900 by David Hilbert. It concerns the expression of positive definite rational functions as sums of quotients of squares. The original question may be reformulated as:

  4. Hilbert's thirteenth problem - Wikipedia

    en.wikipedia.org/wiki/Hilbert's_thirteenth_problem

    Hilbert's thirteenth problem is one of the 23 Hilbert problems set out in a celebrated list compiled in 1900 by David Hilbert. It entails proving whether a solution exists for all 7th-degree equations using algebraic (variant: continuous) functions of two arguments. It was first presented in the context of nomography, and in particular ...

  5. Hilbert's tenth problem - Wikipedia

    en.wikipedia.org/wiki/Hilbert's_tenth_problem

    Hilbert's tenth problem is the tenth on the list of mathematical problems that the German mathematician David Hilbert posed in 1900. It is the challenge to provide a general algorithm that, for any given Diophantine equation (a polynomial equation with integer coefficients and a finite number of unknowns), can decide whether the equation has a solution with all unknowns taking integer values.

  6. Hilbert's program - Wikipedia

    en.wikipedia.org/wiki/Hilbert's_program

    In mathematics, Hilbert's program, formulated by German mathematician David Hilbert in the early 1920s, [1] was a proposed solution to the foundational crisis of mathematics, when early attempts to clarify the foundations of mathematics were found to suffer from paradoxes and inconsistencies. As a solution, Hilbert proposed to ground all ...

  7. Kolmogorov–Arnold representation theorem - Wikipedia

    en.wikipedia.org/wiki/Kolmogorov–Arnold...

    The Kolmogorov–Arnold representation theorem is closely related to Hilbert's 13th problem.In his Paris lecture at the International Congress of Mathematicians in 1900, David Hilbert formulated 23 problems which in his opinion were important for the further development of mathematics. [7]

  8. Hilbert's sixteenth problem - Wikipedia

    en.wikipedia.org/wiki/Hilbert's_sixteenth_problem

    The first part of Hilbert's 16th problem. In 1876, Harnack investigated algebraic curves in the real projective plane and found that curves of degree n could have no more than. separate connected components. Furthermore, he showed how to construct curves that attained that upper bound, and thus that it was the best possible bound.

  9. Entscheidungsproblem - Wikipedia

    en.wikipedia.org/wiki/Entscheidungsproblem

    The Entscheidungsproblem is related to Hilbert's tenth problem, which asks for an algorithm to decide whether Diophantine equations have a solution. The non-existence of such an algorithm, established by the work of Yuri Matiyasevich , Julia Robinson , Martin Davis , and Hilary Putnam , with the final piece of the proof in 1970, also implies a ...
