Optimization problem for star covers of graphs without four cycles
Damjana Kokol Bukovšek, Polona Oblak, Helena Šmigoc
This work presents a study of star covers on graphs. Unlike traditional formulations that minimize the number of stars, our aim is to optimize the number of bipartite components us…
Unital compressed commuting graph of matrices over a finite prime field
Ivan-Vanja Boroja, Damjana Kokol Bukovšek, Nik Stopar
In this paper we completely describe the unital compressed commuting graph of the ring of matrices over the finite prime field $\mathrm…
When does an infinite ring have a finite compressed commuting graph?
Ivan-Vanja Boroja, Damjana Kokol Bukovšek, Nik Stopar
We show that any infinite ring has an infinite nonunital compressed commuting graph. We classify all infinite unital rings with finite unital compressed commuting graph, using semi…
Relation between Blomqvist's beta and other measures of concordance of copulas
Damjana Kokol Bukovšek, Tomaž Košir, Blaž Mojškerc +1
An investigation is presented of how a comprehensive choice of four most important measures of concordance (namely Spearman's rho, Kendall's tau, Spearman's footrule, and Gini's ga…
