Graph and Union of Graphs Compositions
<|reference_start|>Graph and Union of Graphs Compositions: Knopfmacher et all [1] was introduced the graph compositions` notion. In this note we add to these a new construction of tree-like graphs where nodes are graphs themselves. The first examples of these tree-like compositions, a corresponding theorem and resulting conclusions are provided.<|reference_end|>
