Delta in graph theory
WebUppercase delta (Δ) in algebra represents the discriminant of a polynomial equation. This polynomial equation is almost always the quadratic equation. Consider the quadratic ax2+bx=c, the discriminant of this equation would equal b2-4ac, and it would certainly look like this: Δ= b2-4ac.

Theorem 5.8.3 In any graph G, χ ≤ Δ + 1. Proof Note that if d(vn) < Δ, even vn may be colored with one of the colors 1, 2, …, Δ. Since the choice of vn was arbitrary, we may choose vn so that d(vn) < Δ, unless all vertices have degree Δ, that is, if G is regular.
WebSep 17, 2015 · Every graph G contains a path of length δ ( G) and a cycle of length at least δ ( G) + 1 (provided that δ ( G) ≥ 2 ). Following the proof I can see why this would be true if G actually contains a cycle, but I keep thinking there are many graphs, like the path graph itself and connected trees, with δ ( G) ≥ 2 but which don't have any cycles.
