Hensel's Lemma - Statement

Statement

Let be a polynomial with integer (or p-adic integer) coefficients, and let m,k be positive integers such that mk. If r is an integer such that

and

then there exists an integer s such that

and

Furthermore, this s is unique modulo pk+m, and can be computed explicitly as

where

In this formula for t, the division by pk denotes ordinary integer division (where the remainder will be 0), while negation, multiplication, and multiplicative inversion are performed in .

As an aside, if, then 0, 1, or several s may exist (see Hensel Lifting below).

Famous quotes containing the word statement:

    After the first powerful plain manifesto
    The black statement of pistons, without more fuss
    But gliding like a queen, she leaves the station.
    Stephen Spender (1909–1995)

    A sentence is made up of words, a statement is made in words.... Statements are made, words or sentences are used.
    —J.L. (John Langshaw)

    It is commonplace that a problem stated is well on its way to solution, for statement of the nature of a problem signifies that the underlying quality is being transformed into determinate distinctions of terms and relations or has become an object of articulate thought.
    John Dewey (1859–1952)
