Title: A Three-Dimensional Counterexample to Integer-Degree Harmonic Dimension Comparison.

Abstract: For every $4/9{}lt v{}lt 1$ and $1{}lt c{}lt 9v/4$, all sufficiently large integers k admit a complete smooth metric on ℝ3 with nonnegative Ricci curvature, asymptotic volume ratio v, and at least $c(k+1){}2$ linearly independent real harmonic functions of pointwise growth at most k. This answers Yau's integer-degree dimension comparison question negatively in dimension three, with a fixed-factor excess over the Euclidean count. For each $1{}lt c{}lt 9/4$, these metrics can be chosen arbitrarily close to the Euclidean metric in global bi-Lipschitz distance. The metric may depend on k.
