Let ₁,...,ₙ be properties of graphs. A (₁,...,ₙ)-partition of a graph G is a partition of the vertex set V(G) into subsets V₁, ...,Vₙ such that the subgraph G[V_i] induced by V_i has property _i; i = 1,...,n. A graph G is said to be uniquely (₁, ...,ₙ)-partitionable if G has exactly one (₁,...,ₙ)-partition. A property is called hereditary if every subgraph of every graph with property also has property . If every graph that is a disjoint union of two graphs that have property also has property , then we say that is additive. A property is called degenerate if there exists a bipartite graph that does not have property . In this paper, we prove that if ₁,..., ₙ are degenerate, additive, hereditary properties of graphs, then there exists a uniquely (₁,...,ₙ)-partitionable graph.
Keywords: hereditary property of graphs, additivity, reducibility, vertex partition
