  2. Monomorphism - Wikipedia

    en.wikipedia.org/wiki/Monomorphism

    In the more general setting of category theory, a monomorphism (also called a monic morphism or a mono) is a left-cancellative morphism. That is, an arrow f : X → Y such that for all objects Z and all morphisms g 1 , g 2 : Z → X ,

  3. Monic polynomial - Wikipedia

    en.wikipedia.org/wiki/Monic_polynomial

    In algebra, a monic polynomial is a non-zero univariate polynomial (that is, a polynomial in a single variable) in which the leading coefficient (the nonzero coefficient of highest degree) is equal to 1.

  4. Morphism - Wikipedia

    en.wikipedia.org/wiki/Morphism

    A monomorphism can be called a mono for short, and we can use monic as an adjective. [1] A morphism f has a left inverse or is a split monomorphism if there is a morphism g : Y → X such that g ∘ f = id X. Thus f ∘ g : Y → Y is idempotent; that is, (f ∘ g) 2 = f ∘ (g ∘ f) ∘ g = f ∘ g. The left inverse g is also called a ...

    The second fundamental concept of category theory is the concept of a functor, which plays the role of a morphism between two categories and : it maps objects of to objects of and morphisms of to morphisms of in such a way that sources are mapped to sources, and targets are mapped to targets (or, in the case of a contravariant functor, sources ...

    n p(y /a n), where q(y) is a monic polynomial with integer coefficients. If x is an algebraic number then it can be written as the ratio of an algebraic integer to a non-zero algebraic integer. In fact, the denominator can always be chosen to be a positive integer.

  7. Minimal polynomial (linear algebra) - Wikipedia

    In linear algebra, the minimal polynomial μ A of an n × n matrix A over a field F is the monic polynomial P over F of least degree such that P(A) = 0. Any other polynomial Q with Q(A) = 0 is a (polynomial) multiple of μ A. The following three statements are equivalent: λ is a root of μ A, λ is a root of the characteristic polynomial χ A ...

    E.g.: x**2 + 3*x + 5 will be represented as [1, 3, 5] """ out = list (dividend) # Copy the dividend normalizer = divisor [0] for i in range (len (dividend)-len (divisor) + 1): # For general polynomial division (when polynomials are non-monic), # we need to normalize by dividing the coefficient with the divisor's first coefficient out [i ...

    In finite field theory, a branch of mathematics, a primitive polynomial is the minimal polynomial of a primitive element of the finite field GF(p m).This means that a polynomial F(X) of degree m with coefficients in GF(p) = Z/pZ is a primitive polynomial if it is monic and has a root α in GF(p m) such that {,,,,, …} is the entire field GF(p m).
