摘要：

The energy of a graph is defined as the sum of the absolute values of all the eigenvalues of the graph. Let G(n) be the class of bicyclic graphs G on n vertices and containing no disjoint odd cycles of lengths k and l with k + l ≡ 2 (mod 4). In this paper, the graphs in G(n) with minimal, second-minimal and third-minimal energies are determined.
