2011-10-26 15:25:46 +0100 | marked best answer | Factorization of non-commutative Laurent polynomials Sage does not have algorithms to do such a factorization. The notion of unique factorization for noncommutative rings needs a bit more thought than in the commutative case. Work by P.M. Cohn showed that free associative algebra is a (noncommutative) UFD, but I don't know of any algorithm implementing this. |

2011-10-26 02:37:53 +0100 | asked a question | Factorization of non-commutative Laurent polynomials Hi, can Sage factorize non-commutative Laurent polynomials in several variables? By those polynomials I mean elements in the group algebra Z[F(n)], where Z is the integers and F(n) is the free group on n letters. (The case with Z/2- instead of Z-coefficients would also be interesting.) Thank you! |
