Let $c(q)$ denote the optimal constant in the three-dimensional case, and let $c_{3,2}(q)$ be the constant obtained from two equal weights. For $-2<q<-1$, the value of the optimal…

Let $c(q)$ denote the optimal constant in the two-dimensional case, and let $c_{2,2}(q)$ be the constant obtained from two equal weights. For $-1<q<0$, the relevant bound is not kn…
