20.500.12556/RUL-153555 Quasi-copulas as linear combinations of copulas We prove that every quasi-copula can be written as a uniformly converging infinite sum of multiples of copulas. Furthermore, we characterize those quasi-copulas which can be written as a finite sum of multiples of copulas, i.e., that are a linear combination of two copulas. This generalizes a recent result of Fernández-Sánchez, Quesada-Molina, and Úbeda-Flores who considered linear combinations of discrete copulas. quasi-copulas copulas linear combination affine combination Minkowski norm true false true Angleški jezik Ni določen Članek v reviji 2024-01-15 13:41:59 2024-01-15 13:42:00 2024-03-07 09:07:41 0000-00-00 00:00:00 2024 0 0 15 str. art. 108821 Vol. 477 Feb. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.2 0165-0114 10.1016/j.fss.2023.108821 179977731 1-s2.0-S0165011423004669-main.pdf 1-s2.0-S0165011423004669-main.pdf 1 FC9A159EC31592EBF21C778B997A992A accf3148aeb351e3e625f836efdca09bc2dc0c0d4c662eeeb877c9b1b700c8bd bf0e13f2-b3a3-11ee-88ef-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=179610 https://www.sciencedirect.com/science/article/pii/S0165011423004669 1 7a98e358-b3a3-11ee-88ef-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=179609 Fakulteta za elektrotehniko Fakulteta za gradbeništvo in geodezijo 0 0 0
