The energy of a graph, defined as the sum of the absolute values of its eigenvalues, the number of independent edge subsets (known as Hosoya index) and the number of independent vertex subsets (called Merrifield-Simmons index) are three closely related graph invariants that are studied in mathematical chemistry. In this paper, we characterize the unique (up to isomorphism) tree which has a given degree sequence, minimum energy and Hosoya index and maximum Merrifield-Simmons index. We also compare different degree sequences and show how various known results follow as simple corollaries from our main theorem.
