Does anyone know what are the most efficient algorithms for factoring polynomials in a field of characteristic zero, i.e, a field that may contain infinitely many elements. I'm mainly concerned within the context of the field of integers but I wouldn't mind the rationals as well.

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

  • $\begingroup$ What research have you done? Wikipedia has an article on this; have you read it? Have you followed up on its references? In the future I'd expect you to do more research, and to show us what research you've done in the question: if your question is partly or wholly answered by Wikipedia and you were unaware, you haven't done enough research before asking. $\endgroup$ – D.W.

  • $\begingroup$ Also, please edit your question to clarify what you are looking for (since the integers are not a field; they are a ring). Also, are you looking at univariate polynomials or multivariate polynomials? $\endgroup$ – D.W. Jul 18 '14 at 6:05

Do you know of Berlekamp's algorithm and the Cantor–Zassenhaus algorithm?

Unless I'm misunderstanding your question, there is no field of integers- they form a ring but don't have multiplicative inverses
