Recall that a formula is a statement whose truth value may depend on the values of some variables. For example The phrase "for every $x$'' (sometimes "for all $x$'') is called a universal quantifier and is denoted by $\forall x$. The phrase "there exists an $x$ such that'' is called an existential.

I think the shares of Nexstar Media Group are trading at a significant discount, given the sustainability of the dividend.

My understanding is that a quantifier-free formula in FOL is simply a formula that contains no quantifiers, just possibly free How is such a formula interpreted? My understanding is that if we're interested in satisfiability, we agree We can, for example, use a variable assignement function $s.

Let $\mathcal M, \mathcal N$ be $\mathcal L$-structures such that $\mathcal M$ is a substructure of $\mathcal N$. Let $\map \phi {\bar x}$ be a quantifier-free $\mathcal L$-formula, and let $\bar a \in\mathcal M$. Then $\mathcal M \models \map \phi {\bar a}$ if and only if $\mathcal N \models \map.

Given a quantifier-free first-order formula over the theory of ordered fields, our aim is to find an equivalent first-order formula that issimpler. The notion of a formula being simpler will be specified. An overview is given over various methods combining elements of field theory, order theory, and logic.

Each kind of quantification defines a corresponding closure operator on the set of formulas, by adding, for each free variable x, a quantifier to bind x. For example, the existential closure of the open formula n>2 ∧ x n +y n =z n is the closed formula ∃n ∃x ∃y ∃z (n>2 ∧ x n +y n =z n); the latter formula, when interpreted over the.
