A multigraph (or pleograph) is a sequence of letters that behaves as a unit and is not the sum of its parts, such as English ⟨ch⟩ or French ⟨eau⟩. The...

high-degree planar graphs, the number of colors is always Δ, and for multigraphs, the number of colors may be as large as 3Δ/2. There are polynomial time...

the multigraph ΩG, called the power object of G. What is special about a multigraph as an algebra is that its operations are unary. A multigraph has two...

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...

A Latin-script multigraph is a multigraph consisting of characters of the Latin script. digraphs (two letters, as ⟨ch⟩ or ⟨ea⟩) trigraphs (three letters...

permutations; such a pair is sufficient to determine a multigraph, a surface, and a 2-cell embedding of the multigraph onto the surface. Every rotation scheme defines...
