A General Existence Theorem,If . is any subset of the vertex-set . (.) of a graph or multigraph ., we write . to denote the graph constructed by deleting from . all vertices in . and all edges touching then. One can discuss the components of .; they are either . (have an odd number of vertices) or .. Let Φ. (.) denote the number of odd components of ..

One-Factorizations of Multigraphs,The complete multigraph λ.. has . vertices and there are λ edges joining each pair of vertices. One-factors and one-factorizations of λ.. are defined in the obvious way; if . is odd there can be no one-factor, and when . is even, say . = 2., one can produce a one-factorization of λ.. by taking λ copies of each factor in a one-factorization of ...
