Abstract :
Let $mathscr{D}$ be a simple connected digraph with $n$ vertices and $m$ arcs and let $W(mathscr{D})=mathscr{D},w)$ be the weighted digraph corresponding to $mathscr{D}$, where the weights are taken from the set of non-zero real numbers. Let $nu_1,nu_2, dots,nu_n$ be the eigenvalues of the skew Laplacian weighted matrix $widetilde{SL}W(mathscr{D})$ of the weighted digraph $W(mathscr{D})$. In this paper, we discuss the skew Laplacian energy $widetilde{SLE}W(mathscr{D})$ of weighted digraphs and obtain the skew Laplacian energy of the weighted star $W(mathscr{K}_{1, n})$ for some fixed orientation to the weighted arcs. We obtain lower and upper bounds for $widetilde{SLE}W(mathscr{D})$ and show the existence of weighted digraphs attaining these bounds.
