The existence of polynomials which are unrepresentable in Kolmogorov-Arnold superposition representation
Abstract
In this paper, it is proved that there exist polynomials of three complex variables which cannot be represented as any Kolmogorov-Arnold superposition, which has played important roles in the original version of Hilbert's 13th problem.
