The star-discrepancy lower-bound conjecture

Let mm points be chosen in [0,1)d[0,1)^d, and let D(m,d)D(m,d)_\infty denote the infimum of their LL_\infty discrepancy. Star-discrepancy lower-bound conjecture. For d3d\ge 3,

D(m,d)C(d)m1(logm)d1.D(m,d)_\infty \ge C(d)m^{-1}(\log m)^{d-1}.

This is the classical great open problem in discrepancy theory, formulated as an excruciatingly difficult problem; the optimal logarithmic exponent is known in several weaker settings but remains open for the LL_\infty discrepancy in dimensions at least three.
