Graph, edge, and node attributes are propagated to the union graph. If a graph attribute is present in multiple graphs, then the value from the last graph in the list with that attribute is used. union_all ()
Disjoint union of graphs — disjoint_union • igraph
In graph theory, a branch of mathematics, the disjoint union of graphs is an operation that combines two or more graphs to form a larger graph. It is analogous to the disjoint union of sets, and is constructed by making the vertex set of the result be the disjoint union of the vertex sets of the given … See more The disjoint union is also called the graph sum, and may be represented either by a plus sign or a circled plus sign: If $${\displaystyle G}$$ and $${\displaystyle H}$$ are two graphs, then $${\displaystyle G+H}$$ See more Certain special classes of graphs may be represented using disjoint union operations. In particular: • See more WebLet F be the family of graphs that: (1) contains every complete graph of order at least 2; and (2) is closed under attaching general coronas, that is, if a graph G ′ belongs to F and … mckay\u0027s application
