The p-energy of a k-vertex digraph D is defined by E p (D) = ∑ j = 1 k | R (λ j) I (λ j) | , where λ 1 , ... , λ k are eigenvalues of D and R (λ j) and I (λ j) are respectively real and imaginary parts of the eigenvalue λ j. In the present paper, we consider a class of bicyclic digraphs such that each digraph in this class contains two vertex-disjoint directed cycles. We find digraphs in this class with extremal p-energy. [ABSTRACT FROM AUTHOR] |
