Discrepancy-order conjecture for golden-ratio Hammersley point sets

About 3 years old · traced to

Let

denote the golden ratio, let $F$ be the Fibonacci sequence used to define the point-set size, and let $H_m$ be the Hammersley point set in base

containing N=FmN=F^m points, where me0m e 0 is an integer. The quantities L2,N(Hm)L_{2,N}(H_m) and DN∗(Hm)D_N^{*}(H_m) denote, respectively, the L2L_2 discrepancy and star discrepancy.

Discrepancy-order conjecture. For me0m e 0,

L2,N(Hm)=Θ(log⁡NN)L_{2,N}(H_m)=\Theta\left(\frac{\log N}{N}\right)

and

DN∗(Hm)=Θ(log⁡NN).D_N^{*}(H_m)=\Theta\left(\frac{\log N}{N}\right).

The claim is motivated by numerical evidence from the discrepancy plots and is stated as strong evidence for the displayed convergence; no proof or resolution is supplied in the paper.
