Sums of almost equal prime squares
Résumé
In this short note, we prove that almost all integers $N$ satisfying $N\equiv 3\,({\rm mod}\,24)$ and $5\nmid N$ or $N\equiv 4\,({\rm mod}\,24)$ is the sum of three or four almost equal prime squares, respectively: $N=p_1^2+\cdots+p_j^2$ with $|p_i-(N/j)^{1/2}|\leq N^{1/2-9/80+\varepsilon}$ for $j=3$ or $4$ and $1\leq i\leq j$.
