20.500.12556/RUL-182583 A complete characterization of maximal copulas with given track section Bivariate copulas with prescribed diagonal section were first studied by Bertino. Their maximality was studied so far only from the point of view of upper bounds which brings quasi-copulas into the picture and limits the resulting set substantially. We propose to study maximality of these families in the order theoretic sense. A copula $C$ with given diagonal section $\delta$ is called undominated if there is no copula $C' \ne C$ with the same diagonal section $\delta$ such that $C \le C'$. The main contribution of this paper is a new method that provides undominated copulas. They form a much wider class that contains the known upper bounds as a very small subclass. There was a recent call for the study of asymmetry which is addressed by our class better than by the known ones. Corresponding quasi-copulas can be obtained from our copulas via splicing techniques. Most results are given on the level of tracks. bivariate copulas quasi-copulas diagonal section track section undominated copulas matematika verjetnosti true false true Angleški jezik Slovenski jezik Članek v reviji 2026-05-18 11:32:45 2026-05-18 11:32:50 2026-06-05 03:02:02 0000-00-00 00:00:00 2026 0 0 15 str. art. 109949 Vol. 541 Oct. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.2 0165-0114 10.1016/j.fss.2026.109949 278471427 Skulj_Omladic_FS&S_koncna.pdf Skulj_Omladic_FS&S_koncna.pdf 1 FB4FFD7611B7B3647AC91746F9E9E11D 890072485ea6063a83424b24c50a1e2d8fd3dcf076f9aa0629618845afda1fba c12c2957-5fec-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=234945 https://www.sciencedirect.com/science/article/pii/S0165011426001879 0 aa349e20-529c-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=233971 Fakulteta za družbene vede Fakulteta za matematiko in fiziko 0 0 0
