Hilbert's thirteenth problem is one of the 23 problems proposed by the German mathematician David Hilbert in 1900. Specifically, the problem is concerned with the nature of continuous functions and their representations. Hilbert's thirteenth problem asks whether every continuous function of two variables can be represented as a composition of continuous functions of one variable.
