On the square of an oriented graph conjecture
In 1993, Paul Seymour posed the problem that for every oriented graph G there exist a vertex whose out-degree at least doubles when you square the oriented graph; that is, if G = (V (G), A(G)) and denote δ+G (x) to be the out-degree of vertex x in the graph G, then there exists x ∈ (G) such that δ+(...
