has gloss | eng: In the mathematical field of set theory, a large cardinal property is a certain kind of property of transfinite cardinal numbers. Cardinals with such properties are, as the name suggests, generally very "large" (for example, bigger than aleph zero, bigger than the cardinality of the continuum, etc.). The proposition that such cardinals exist cannot be proved in the most common axiomatization of set theory, namely ZFC, and such propositions can be viewed as ways of measuring how "much", beyond ZFC, one needs to assume to be able to prove certain desired results. In other words, they can be seen, in Dana Scott's phrase, as quantifying the fact "that if you want more you have to assume more". |

has gloss | ces: Velké kardinály či velká kardinální čísla je v teorii množin souhrnné označení pro kardinální čísla, jejichž existence je nezávislá na axiomech Zermelo-Fraenkelovy teorie s axiomem výběru (ZFC). Existence či neexistence každého z těchto čísel má v ZF závažné důsledky týkající se zejména nekonečné kombinatoriky. Často však přijetí axiomu postulujícího existenci nějakého velkého kardinálu zásadně ovlivňuje vlastnosti o kardinálech malých (\alef_1, \alef_2, …). |

has gloss | deu: * \kappa heißt schwach unerreichbare Kardinalzahl, wenn sie überabzählbarer, regulärer Limes ist, wenn also \mathrmcf} (\kappa) = \kappa > \omega (cf steht für Konfinalität) gilt und für jedes \mu < \kappa auch \mu^+ < \kappa. Schwach unerreichbare Kardinalzahlen sind genau die regulären Fixpunkte der Aleph-Reihe: \aleph_\kappa = \kappa = \mathrmcf} (\kappa). * \kappa heißt stark unerreichbare Kardinalzahl, wenn \kappa überabzählbarer, regulärer starker Limes ist, wenn also \mathrmcf} (\kappa) = \kappa > \omega gilt und für jedes \mu < \kappa auch 2^\mu < \kappa. Stark unerreichbare Kardinalzahlen sind genau die regulären Fixpunkte der Beth-Reihe: \beth_\kappa = \kappa = \mathrmcf} (\kappa). |

has gloss | fra: En mathématiques, et plus précisément en théorie des ensembles, un grand cardinal est un nombre cardinal transfini satisfaisant une propriété qui le distingue des ensembles constructibles avec laxiomatique usuelle (ZFC) tels que aleph zéro, aleph-ω, etc., et le rend nécessairement plus grand que tous ceux-ci. Lexistence dun grand cardinal est donc soumise à lacceptation de nouveaux axiomes. |

has gloss | pol: Duże liczby kardynalne (ang. large cardinals) – liczby kardynalne których istnienia nie można udowodnić w ZFC i co więcej takie, dla których niesprzeczność istnienia nie wynika z niesprzeczności ZFC, a jednocześnie można wykazać niesprzeczność nieistnienia tych liczb. |

has gloss | por: No campo matemático da teoria dos conjuntos, uma propriedade de grande cardinal é um certo tipo de propriedade de números cardinais transfinitos. Cardinais com tais propriedades, como o nome sugere, são muito "grandes" (por exemplo, maior que aleph (a cardinalidade dos números naturais), maiores que a cardinalidade do contínuo, et cetera). |
