Abstract

In this paper three criteria for the height of an atom in terms of its \(f\)-graph are established. The obstacles to the oriented embeddability of the \(f\)-graph into the plane are found. The combinatorial properties of labeled oriented cycles, which are a generalization of chord diagrams, are investigated.

原子高度的标准

摘要

在本文中，针对原子的\（f \）图建立了三个高度标准。发现了\（f \）图定向嵌入平面的障碍。研究了标记的定向循环的组合特性，该定向特性是弦图的一般化。
