Conceitos essenciais
本文推廣了 Boris Delaunay 關於空外接球單形的經典結果,證明了對於一個局部有限且粗略密集的歐式空間點集,空間中幾乎每個點都包含在相同數量的 k-heavy 單形中,這些單形的頂點屬於該點集,且其外接球恰好包含該點集中的 k 個點。
Estatísticas

"In this paper, we generalize Delaunay’s construction and prove similar properties for simplices with circumspheres that enclose exactly k points of A, for some fixed non-negative integer k. We call these simplices the k-heavy simplices of A."
