  2. Function composition - Wikipedia

    en.wikipedia.org/wiki/Function_composition

    If an airplane's altitude at time t is a(t), and the air pressure at altitude x is p(x), then (p ∘ a)(t) is the pressure around the plane at time t. Function defined on finite sets which change the order of their elements such as permutations can be composed on the same set, this being composition of permutations.

  3. Absolutely and completely monotonic functions and sequences

    en.wikipedia.org/wiki/Absolutely_and_completely...

    A function that is absolutely monotonic on [,) can be extended to a function that is not only analytic on the real line but is even the restriction of an entire function to the real line. The big Bernshtein theorem : A function f ( x ) {\displaystyle f(x)} that is absolutely monotonic on ( − ∞ , 0 ] {\displaystyle (-\infty ,0]} can be ...

  4. Composition algebra - Wikipedia

    en.wikipedia.org/wiki/Composition_algebra

    The possible dimensions of a composition algebra are 1, 2, 4, and 8. [2] [3] [4] 1-dimensional composition algebras only exist when char(K) ≠ 2. Composition algebras of dimension 1 and 2 are commutative and associative. Composition algebras of dimension 2 are either quadratic field extensions of K or isomorphic to K ⊕ K.

  5. Category of sets - Wikipedia

    en.wikipedia.org/wiki/Category_of_sets

    The arrows or morphisms between sets A and B are the functions from A to B, and the composition of morphisms is the composition of functions. Many other categories (such as the category of groups, with group homomorphisms as arrows) add structure to the objects of the category of sets or restrict the arrows to functions of a particular kind (or ...

  6. Algebraic function - Wikipedia

    en.wikipedia.org/wiki/Algebraic_function

    A composition of transcendental functions can give an algebraic function: = ⁡ ⁡ =. As a polynomial equation of degree n has up to n roots (and exactly n roots over an algebraically closed field , such as the complex numbers ), a polynomial equation does not implicitly define a single function, but up to n functions, sometimes also called ...

  7. Norm (mathematics) - Wikipedia

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

    A composition algebra (,,) consists of an algebra over a field, an involution, and a quadratic form = called the "norm". The characteristic feature of composition algebras is the homomorphism property of N {\displaystyle N} : for the product w z {\displaystyle wz} of two elements w {\displaystyle w} and z {\displaystyle z} of the composition ...

  8. Function (mathematics) - Wikipedia

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

    The Church–Turing thesis is the claim that every philosophically acceptable definition of a computable function defines also the same functions. General recursive functions are partial functions from integers to integers that can be defined from constant functions, successor, and; projection functions; via the operators composition,

  9. Hurwitz's theorem (composition algebras) - Wikipedia

    en.wikipedia.org/wiki/Hurwitz's_theorem...

    Let A be a Euclidean Hurwitz algebra and B a proper unital subalgebra, so a Euclidean Hurwitz algebra in its own right. Pick a unit vector j in A orthogonal to B. Since (j, 1) = 0, it follows that j* = −j and hence j 2 = −1. Let C be subalgebra generated by B and j. It is unital and is again a Euclidean Hurwitz algebra.
