De Bruijn–Erdős theorem (graph theory) — This article is about coloring infinite graphs. For the number of lines determined by a finite set of points, see De Bruijn–Erdős theorem (incidence geometry). In graph theory, the De Bruijn–Erdős theorem, proved by Nicolaas Govert de Bruijn and… … Wikipedia
Weakly compact cardinal — In mathematics, a weakly compact cardinal is a certain kind of cardinal number introduced by harvtxt|Erdös|Tarski|1961; weakly compact cardinals are large cardinals, meaning that their existence can neither be proven nor disproven from the… … Wikipedia

Théorème d'Erdős-Kaplansky — En mathématiques, plus précisément en algèbre linéaire, on sait qu un espace vectoriel E de dimension finie est isomorphe à son dual. En revanche, si E est de dimension infinie, il n est jamais isomorphe à son dual. Cela résulte du théorème d… … Wikipédia en Français
List of large cardinal properties — This page is a list of some types of cardinals; it is arranged roughly in order of the consistency strength of the axiom asserting the existence of cardinals with the given property. Existence of a cardinal number κ of a given type implies the… … Wikipedia

Chang's conjecture — In model theory, a branch of mathematical logic, Chang s conjecture, attributed to Chen Chung Chang by Vaught (1963, p. 309), states that every model of type (ω2,ω1) for a countable language has an elementary submodel of type (ω1, ω). A… … Wikipedia
Indiscernibles — In mathematical logic, indiscernibles are objects which cannot be distinguished by any property or relation defined by a formula. Usually only first order formulas are considered. For example, if {A, B, C} is indiscernible, then for each 2 ary… … Wikipedia
