  2. Hypernymy and hyponymy - Wikipedia

    en.wikipedia.org/wiki/Hypernymy_and_hyponymy

    For example, screwdriver, scissors, knife, and hammer are all co-hyponyms of one another and hyponyms of tool, but not hyponyms of one another: *"A hammer is a type of knife" is false. Co-hyponyms are often but not always related to one another by the relation of incompatibility. For example, apple, peach and plum are co-hyponyms of fruit.

  3. Limit (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Limit_(mathematics)

    In mathematics, a limit is the value that a function (or sequence) approaches as the argument (or index) approaches some value. [1] Limits of functions are essential to calculus and mathematical analysis, and are used to define continuity, derivatives, and integrals.

  4. Real Life (novel) - Wikipedia

    en.wikipedia.org/wiki/Real_Life_(novel)

    Real Life is Taylor's first novel; he is a "scientist turned novelist" who did his undergraduate studies at Auburn University Montgomery. [2] Charles Arrowsmith, writing for The Washington Post, said that "Like many first novels, Real Life appears to hew to its author's own experience—Taylor has written in numerous personal essays about being gay and Southern, his abusive upbringing and his ...

    This principle, foundational for all mathematics, was first elaborated for geometry, and was systematized by Euclid around 300 BC in his book Elements. [ 21 ] [ 22 ] The resulting Euclidean geometry is the study of shapes and their arrangements constructed from lines, planes and circles in the Euclidean plane ( plane geometry ) and the three ...

  7. Direct limit - Wikipedia

    en.wikipedia.org/wiki/Direct_limit

    In mathematics, a direct limit is a way to construct a (typically large) object from many (typically smaller) objects that are put together in a specific way. These objects may be groups, rings, vector spaces or in general objects from any category.

  9. Real algebraic geometry - Wikipedia

    en.wikipedia.org/wiki/Real_algebraic_geometry

    Nowadays the words 'semialgebraic geometry' and 'real algebraic geometry' are used as synonyms, because real algebraic sets cannot be studied seriously without the use of semialgebraic sets. For example, a projection of a real algebraic set along a coordinate axis need not be a real algebraic set, but it is always a semialgebraic set: this is ...
