Abstract
We construct irrational irreducible components of the Hilbert scheme of points of affine space A n 𝔸n double struck upper A Superscript n for n ≥ 12 n ≥ 12 n greater than or equals 12 . We start with irrational components of the Hilbert scheme of curves in CP 3 ℂℙ3 double struck upper C upper P cubed and use methods developed by Jelisiejew to relate these to irreducible components of the Hilbert schemes of points of A n 𝔸n double struck upper A Superscript n . The result solves Problem XX of the Hilbert scheme of points problem list [J24].
