Fuzzy Sets and Systems, 2022 We study the extreme points (in the Krein-Milman sense) of the class of semilinear copulas and provide their characterization. Related results into the more general setting of conjunctive aggregation functions (i.e, semi--copulas and quasi--copulas) are also presented.

On bivariate lower semilinear copulas and the star product
International Journal of Approximate ReasoningWe revisit the family $\mathcal{C}^{LSL}$ of all bivariate lower semilinear (LSL) copulas first introduced by Durante et al. in 2008 and, using the characterization of LSL copulas in terms of diagonals with specific properties, derive several novel and partially unexpected results.

International Journal of Approximate ReasoningWe explore how the classical concordance measures - Kendall's $τ$, Spearman's rank correlation $ρ$, and Spearman's footrule $ϕ$ - relate to Chatterjee's rank correlation $ξ$ when restricted to lower semilinear copulas. First, we provide a complete characterization of the attainable $τ$-$ρ$ region for this class, thus resolving the conjecture in [18 ...

On copulas that generalize semilinear copulas
Kybernetika, 2012Summary: We study a wide class of copulas which generalizes well-known families of copulas, such as the semilinear copulas. We also study corresponding results for the case of quasi-copulas.

Advances in Data Science and Adaptive Analysis
Copulas are quite a popular, flexible, and useful tool for multivariate modeling in many fields of applications, including finance and insurance, actuarial sciences, biomedical studies, geostatistics, and hydrology. In this paper, we use the concept of diagonal function to build new bivariate copulas based on the well known and important Ali–Mikhail ...
