Hilbert's sixteenth problem
WebHilbert's problem was first solved on the basis of ideas by using technique developed by A. Kronrod [ 14 ]. In this way Kolmogorov proved that any continuous function of n ≥ 4 variables can be represented as a superposition of continuous functions of three variables [ 11 ]. For an arbitrary function of four variables the representation has the form WebThe 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.
