In this study, we introduce a bipartite graph associated to elements and equivalence classes of a heap. We find some invariant numbers of the graph. Furthermore, we associate the graph properties of the graph of domain and codomain of surjective heap morphism. We also investigate the tensor product of the bipartite graph of heaps. © 2024, Universiti Putra Malaysia. All rights reserved.
