A note on orientations of mixed graphs [PDF]
The authors study an orientation problem on mixed graphs. The goal is to obtain a directed graph satisfying a certain connectivity requirement. First the authors continue the study of the pair connectivity problem and show that it is NP-complete for mixed graphs. Then they prove several results for two pairs of nodes of mixed graphs.

Hermitian-Randić matrix and Hermitian-Randić energy of mixed graphs [PDF]
Let M be a mixed graph and H ( M ) $H(M)$ be its Hermitian-adjacency matrix. If we add a Randić weight to every edge and arc in M, then we can get a new weighted Hermitian-adjacency matrix. What are the properties of this new matrix?

Total mixed domination in graphs
For a graph [Formula: see text] we call a subset [Formula: see text] a total mixed dominating set of G if each element of [Formula: see text] is either adjacent or incident to an element of S, and the total mixed domination number of G is the minimum ...

Bivariate Chromatic Polynomials of Mixed Graphs [PDF]
The bivariate chromatic polynomial $\chi_G(x,y)$ of a graph $G = (V, E)$, introduced by Dohmen-P\"{o}nitz-Tittmann (2003), counts all $x$-colorings of $G$ such that adjacent vertices get different colors if they are $\le y$. We extend this notion to

𝕮-inverse of graphs and mixed graphs
This article introduces a generalization of the concept of inverse graphs applicable to both graphs and mixed graphs. Given a graph GG with adjacency matrix A(G)A\left(G), the inverse graph G−1{G}^{-1} is defined such that its adjacency matrix is similar
