On singular values and trace norm of signed digraphs

Mushtaq A. Bhat, Peer Abdul Manan

Let $S = (D, I ¨ )$ be a signed digraph, where $D = (V, A)$ is the underlying digraph of $S$ and $I ¨ : A \to {- 1, + 1}$ is a sign function. In this pap…

On digraphs determined by their singular values

Mushtaq A. Bhat, Peer Abdul Manan

Let $D$ be an digraph of order $n$ with adjacency matrix $A (D)$ and outdegree matrix $I^^{+} = I^^{+} (D)$ . Then the Laplacian and signless Laplacian matrices of $D$ are respectively defi…
