spanning trees –selfsimilar graphsThe number of spanning trees of a graph, also known as the complexity, is computed for graphs constructed by a replacement procedure yielding a self-similar structure. It is shown that under certain symmetry conditions exact formulas for the complexity can be ...
examples that the theorem of Gutman, Mallion and Essam (1983, Molec. Phys., 50, 859), for computing the number of spanning trees in a labelled graph, is generally valid only for planar graphsi.e., those that may be embedded, without crossings, in a plane or on the surface of a ...
In a certain family of graphs, a graph is called minimizing (or second minimizing) if the least eigenvalue of its adjacency matrix attains the minimum (or second minimum). In this paper, we characterize the second minimizing graph among all graphs which belong to the set of complements of ...

The baobab trees (genus Adansonia) have attracted tremendous attention because of their striking shape and distinctive relationships with fauna1. These spectacular trees have also influenced human culture, inspiring innumerable arts, folklore and traditi
These two concepts are equivalent in the sense that r(G)+η(G)=|V(G)|. We denote by v(G) and e(G) the vertex number and the edge number of a graph G, respectively. If the rank of a graph G equals its vertex number we say G is nonsingular. We denote e(G)−v(G)+θ(...
Despite early domestication around 3000 BC, the evolutionary history of the ancient allotetraploid species Brassica juncea (L.) Czern & Coss remains uncertain. Here, we report a chromosome-scale de novo assembly of a yellow-seeded B. juncea genome by
1310.As there have been so many different styles of Western art, it is impossible to describe them all in a short text. 由于西方的艺术风格多种多样,在短短的一篇课文里不可能进行全面的描述。 1311.Perhaps the best way to understand Western a...
