抽象的。对于带有度量的有限度量空间V $ \ rho $,令v n是(a1,……An)和(b1,... bn)之间的距离的度量空间 $ \ sum^{n} _ {i = 1} \ rho(a_i,b_i)$。我们获得了一个渐近公式的对数的渐近公式,该对数的最大值数量是距离v n的最大点,至少从v n点的一半点开始,当n倾向于无穷大和d满足时 $ d \ gg \ sqrt {n} $。
Abstract. For a finite metric space V with a metric $ \rho $, let V n be the metric space in which the distance between (a1, . . ., an) and (b1, . . ., bn) is the sum $ \sum^{n}_{i = 1} \rho (a_i, b_i) $. We obtain an asymptotic formula for the logarithm of the maximum possible number of points in V n of distance at least d from a set of half the points of V n, when n tends to infinity and d satisfies $ d \gg \sqrt {n} $.
