WebIn electrical engineering, the Y-Δ transform, also written wye-delta and also known by many other names, is a mathematical technique to simplify the analysis of an electrical network.The name derives from the shapes of the circuit diagrams, which look respectively like the letter Y and the Greek capital letter Δ.This circuit transformation theory was … WebFeb 8, 2024 · Question: For which fixed values of $\Delta$ is the complexity of $(\Delta-1)$-coloring graphs of maximum degree $\Delta$ known? Motivation: I would have initially thought that, since this is NP-hard for $\Delta=4$, it would be NP-hard for all larger values of $\Delta$. However, it turns out that this is false!

In graph theory, the degree (or valency) of a vertex of a graph is the number of edges that are incident to the vertex; in a multigraph, a loop contributes 2 to a vertex's degree, for the two ends of the edge. The degree of a vertex $${\displaystyle v}$$ is denoted $${\displaystyle \deg(v)}$$ See more The degree sum formula states that, given a graph $${\displaystyle G=(V,E)}$$, $${\displaystyle \sum _{v\in V}\deg(v)=2 E \,}$$. The formula implies that in any undirected graph, the number … See more • A vertex with degree 0 is called an isolated vertex. • A vertex with degree 1 is called a leaf vertex or end vertex or a pendant vertex, and the edge incident with that vertex is called a pendant edge. In the graph on the right, {3,5} is a pendant edge. This terminology is … See more • Indegree, outdegree for digraphs • Degree distribution • Degree sequence for bipartite graphs See more The degree sequence of an undirected graph is the non-increasing sequence of its vertex degrees; for the above graph it is (5, 3, 3, 2, 2, 1, 0). The degree sequence is a See more • If each vertex of the graph has the same degree k, the graph is called a k-regular graph and the graph itself is said to have degree k.
