Drazin Inverses and Walk Structure of Oriented Dutch Windmill Graphs
C. Mendes Araújo, Faustino Maciala, Pedro Patrício
We investigate the Drazin invertibility of adjacency matrices associated with a class of oriented graphs known as oriented Dutch windmill graphs. By analyzing walks of prescribed l…

On generalized inverses of matrices associated with certain graph classes
Cláudia M. Araújo, Faustino A. Maciala, Pedro Patrício
We investigate generalized inverses of matrices associated with two classes of digraphs: double star digraphs and D-linked stars digraphs. For double star digraphs, we determine th…
