- A non-trivial graph is any graph that contains more than one vertex. In other words, it consists of at least two distinct points (vertices) that may or may not be connected by edges. Non-trivial graphs exhibit a more complex structure with a higher degree of connectivity between their vertices compared to trivial graphs.

Jan 2, 2017 · A non-trivial connected graph is any connected graph that isn't this graph. A non-trivial connected component is a connected component that isn't the trivial graph, which is another way of say that it isn't an isolated point.

Jul 17, 2015 · I use empty graph to mean a graph without edges, and therefore a nonempty graph would be a graph with at least one edge. According to both wikipedia.com and wikibooks.com, a trivial graph is a graph with 1 vertex and 0 edges.
4 GRAPH THEORY { LECTURE 1 INTRODUCTION TO GRAPH MODELS Proposition 1.1. A non-trivial simple graph G must have at least one pair of vertices whose degrees are equal. Proof. pigeonhole principle Theorem 1.2 (Euler’s Degree-Sum Thm). The sum of the degrees of the vertices of a graph is twice the number of edges. Corollary 1.3.

However, a major innovation in economic theory has been the use of methods stemming from graph theory to describe and study relations between economic agents in networks. This recent development has lead to a fast increase in theoretical research on economic networks.
Abstract: We introduce a graph-theoretic generalization of classical Arrow-Debreu economics, in which an undirected graph specifies which consumers or economies are permitted to engage in direct trade, and the graph topology may give rise to local variations in the prices of com-modities.
Many nontrivial predictions of microeconomics (for example, whether demand systems have the property of Slutsky symmetry) turn out to fail when agents are boundedly rational, though more trivial predictions (for example, demand curve slope down) typically hold.
These items in Table 1 show that the sales of the two industries to themselves and to each other might be described as “non-GNP” items. The ‘final demand’ column represents the output side of GNP, and the labour row represents the factor-cost side.
