The smooth LpL_{\mathbf p}-discrepancy lower-bound conjecture

About 8 years old · traced to

For a point set ξ\xi with mm points in the dd-dimensional domain and arbitrary weights, let D~pr,o(m,d)\widetilde D^{r,o}_{\mathbf p}(m,d) denote the infimum of the smooth LpL_{\mathbf p}-discrepancy over all such point-weight pairs. Smooth LpL_{\mathbf p}-discrepancy lower-bound conjecture. For all d,r∈Nd,r\in\mathbb N,

D~∞r,o(m,d)≥C(r,d)m−r(log⁡m)d−1.\widetilde D^{r,o}_\infty(m,d) \ge C(r,d)m^{-r}(\log m)^{d-1}.

The conjecture is supported by a theorem proving the same order under a bounded-weight condition. Its unrestricted weighted form remains open.
