The effect on A α -eigenvalues of mixed graphs and unit gain graphs by adding edges in clusters

Linear and multilinear algebra, 2021
Given a simple graph G, a -cluster of G is a pair of vertex subsets , where size of C is and every vertex in C shares the same set S of s neighbours. Let be a mixed graph whose underlying graph G contains a -cluster and let be a mixed graph on c vertices.

Fuzzy mixed graphs and its application to identification of COVID19 affected central regions in India

Journal of Intelligent & Fuzzy Systems, 2020
In the recent phenomenon of social networks, both online and offline, two nodes may be connected, but they may not follow each other. Thus there are two separate links to be given to capture the notion.

Maximum Reachability Orientation of Mixed Graphs

arXiv.org
We aim to find orientations of mixed graphs optimizing the total reachability, a problem that has applications in causality and biology. For given a digraph $D$, we use $P(D)$ for the set of ordered pairs of distinct vertices in $V(D)$ and we define ...
