Topic: Polynomial factorization

  Polynomial Factorization
A polynomial is of degree k if the largest power of the variable in any term is no greter than k.
A polynomial with integer coefficients is "prime" if it cannot be expressed as the product of two lower-degree polynomials with integer coefficients.
The polynomials must be printed in increasing order of degree, and when two or more degrees match they must be sorted by increasing value of coefficients from the greatest to the lowest degree.

  Irreducible polynomial -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: )
See also ((mathematics) the resolution of an integer or polynomial into factors such that when multiplied together they give the integer or polynomial) factorization.
Hence, all irreducible polynomials are of degree 1.
One can show that every (A number that has no factor but itself and 1) prime element is irreducible; the converse is not true in general but holds in (additional info and facts about unique factorization domain) unique factorization domains.

Estimating factorization time.'' This was a talk on estimating the speed of the quadratic sieve and the number field sieve.
The number-field sieve tries to factor an integer n by inspecting values of the homogeneous form of a polynomial related to n.
``Polynomial selection for the number-field sieve, part 2: polynomial merit.'' Abstract written after the talk: ``I discussed the smoothness of the values (a-bm)(a^5+f_4 a^4 b+...+f_0 b^5) that appear in the number-field sieve.

The basic idea underlying this method is the reduction of polynomial factorization over algebraic extension fields to the factorization over the rational number field via linear transformation and the computation of characteristic sets with respect to a proper variable ordering.
Let f1,andhellip;,fk be k multivariate polynomials which have a finite number of common zeros in the algebraic closure of the ground field, counting the common zeros at infinity.
When all the polynomials have the same degree, the complexity of this algorithm is polynomial relative to the generic number of solutions.
