Norm estimates for inverses of Euclidean distance matrices
An estimate for the norm of inverses of Euclidean distance matrices \((\| x_ j-x_ k\|)\) (where \(x_ 1,\dots,x_ n\) are \(n\) distinct points in \(\mathbb{R}^ d)\) is obtained for all dimensions \(d\). For \(d=3\) this estimate is better than Ball's one [\textit{K. Ball}, J. Approximation Theory 68, No. 1, 74-82 (1992; Zbl 0746.41002)].
