\hypertarget{idea}{}\subsection*{{Idea}}\label{idea} \textbf{Generalized quantifiers} were introduced into [[model theory]] by the Polish logician A. Mostowski in order to supplement the usual [[existential quantifier|existential]] and [[universal quantifiers]] of [[first-order logic|first-order predicate logic]] with the aim to circumvent shortcomings concerning expressivity and categoricity. Their use for the [[semantics|semantic]] analysis of natural language determiners in the footsteps of [[Richard Montague]] revolutionized [[linguistics]] in the early 1970s. \hypertarget{definition}{}\subsection*{{Definition}}\label{definition} \begin{defn} \label{GeneralizedQuantifier}\hypertarget{GeneralizedQuantifier}{} A \emph{generalized quantifier} or an \emph{interpretation of a quantifier symbol} $Q$ is a mapping $\mu_Q$ from triples of cardinal numbers $\langle \mathfrak{m},\mathfrak{n},\mathfrak{p}\rangle$ such that $\mathfrak{m}+\mathfrak{n}=\mathfrak{p}$ to $\Omega=\{0,1\}$. The satisfaction relation for $Q$ is defined for structures $\mathfrak{A}$ with carrier $A$ and valuation $x$ by \begin{displaymath} \begin{aligned} \mathfrak{A}\models_x(Qv_n)\phi\quad&{iff}\quad \mu_Q(\mathfrak{m},\mathfrak{n},\mathfrak{p})=1\;,\; with \\ \mathfrak{m}&=card(\{a\in A:\mathfrak{A}\models_{x(n/a)}\phi\}) \\ \mathfrak{n}&=card(\{a\in A:\mathfrak{A}\models_{x(n/a)}\not\phi\}) \\ \mathfrak{p}&=card(A)\;. \end{aligned} \end{displaymath} \end{defn} \hypertarget{examples}{}\subsection*{{Examples}}\label{examples} \begin{itemize}% \item The [[universal quantifier]] $\forall$ has $\mu_\forall(\mathfrak{m},\mathfrak{n},\mathfrak{p})=1$ iff $\mathfrak{n}=0$. \item The quantifier $Q_\alpha$ ``there exist at least $\aleph_\alpha$'' is given by $\mu_{Q_\alpha}(\mathfrak{m},\mathfrak{n},\mathfrak{p})=1$ iff $\mathfrak{m}\geq\aleph_{\alpha}\;$. \item The quantifier $\mathsf{W}$ ``most'' is given by $\mu_{\mathsf{W}}(\mathfrak{m},\mathfrak{n},\mathfrak{p})=1$ iff $\mathfrak{m}>\mathfrak{n}\;$. Note that this uses the second variable as well, whereas $\forall$ or $Q_\alpha$ depend only on $card(\{a\in A:\mathfrak{A}\models_{x(n/a)}\phi\})$. \end{itemize} \hypertarget{related_entries}{}\subsection*{{Related entries}}\label{related_entries} \begin{itemize}% \item [[model theory]] \item [[second-order logic]] \item [[cardinal number]] \item [[Lawvere distribution]] \item [[Richard Montague]] \end{itemize} \hypertarget{references}{}\subsection*{{References}}\label{references} Generalized quantifiers were introduced in \begin{itemize}% \item A.
