2013-10-18 15:19:35 +0100 | answered a question | Ideals of non-commutative polynomials What you're asking for doesn't exist in complete generality because this would imply a solution to the word problem. The GAP package GBNP implements Grobner bases for non-commutative polynomial rings. The algorithm need not terminate, but when it does it solves the problem you're asking about. |

2012-01-12 19:49:07 +0100 | asked a question | How can I construct graded algebras? I am trying to create a graded algebra using generators and relations. I found that sage has a category for such things: http://www.sagemath.org/doc/reference/sage/categories/graded_modules_with_basis.html but there are no constructors or examples of how to create these things. Does anyone know where I can find examples of how to construct graded algebras, or more generally how to construct non-commutative algebras? |
