  2. Existential clause - Wikipedia

    en.wikipedia.org/wiki/Existential_clause

    Some languages form the negative of existential clauses irregularly; for example, in Russian, есть yest ("there is/are") is used in affirmative existential clauses (in the present tense), but the negative equivalent is нет nyet ("there is/are not"), used with the logical subject in the genitive case.

  3. Existential graph - Wikipedia

    en.wikipedia.org/wiki/Existential_graph

    An existential graph is a type of diagrammatic or visual notation for logical expressions, created by Charles Sanders Peirce, who wrote on graphical logic as early as 1882, [1] and continued to develop the method until his death in 1914. They include both a separate graphical notation for logical statements and a logical calculus, a formal ...

  4. Existentially closed model - Wikipedia

    en.wikipedia.org/wiki/Existentially_closed_model

    The existential closure in K of a member M of K, when it exists, is, up to isomorphism, the least existentially closed superstructure of M. More precisely, it is any extensionally closed superstructure M ∗ of M such that for every existentially closed superstructure N of M , M ∗ is isomorphic to a substructure of N via an isomorphism that ...

    That is, every problem in the existential theory of the reals has a polynomial-time many-one reduction to an instance of one of these problems, and in turn these problems are reducible to the existential theory of the reals. [4] [17] A number of problems of this type concern the recognition of intersection graphs of a certain type.

  6. Existential quantification - Wikipedia

    en.wikipedia.org/wiki/Existential_quantification

    In predicate logic, an existential quantification is a type of quantifier, a logical constant which is interpreted as "there exists", "there is at least one", or "for some". It is usually denoted by the logical operator symbol ∃, which, when used together with a predicate variable, is called an existential quantifier (" ∃ x " or " ∃( x ...

  7. Situation semantics - Wikipedia

    en.wikipedia.org/wiki/Situation_semantics

    In situation theory, situation semantics (pioneered by Jon Barwise and John Perry in the early 1980s) [1] attempts to provide a solid theoretical foundation for reasoning about common-sense and real world situations, typically in the context of theoretical linguistics, theoretical philosophy, or applied natural language processing,

  8. Substantial form - Wikipedia

    en.wikipedia.org/wiki/Substantial_form

    Substantial form is a central philosophical concept in Aristotelianism and, afterwards, in Scholasticism. The form is the idea , existent or embodied in a being, that completes or actualizes the potentiality latent in the matter composing the being itself.

  9. Situation theory - Wikipedia

    en.wikipedia.org/wiki/Situation_theory

    Types in the theory are defined by applying two forms of type abstraction, starting with an initial collection of basic types. Basic types: TIM: the type of a temporal location; LOC: the type of a spatial location; IND: the type of an individual; RELn: the type of an n-place relation; SIT: the type of a situation; INF: the type of an infon
