2013-07-08 11:13:26 +0200 | answered a question | ideal primality in a polynomial ring with integer coefficients I don't know how to do it in Sage, but the answer to the second part of your question (i.e. the theory) is in: P. Gianni, B. Trager, G. Zacharias "Groebner bases and primary decomposition of polynomial ideals" JSC 6/1988, 149-167 The same algorithm is AFAIR also in W. Adams, Ph. Loustaunau "Introduction to Groebner Bases" Returning to the first part of your question - Sage uses Singular internally. I think Singular has an appropriate built-in. Hence, I think you will have to "tunnel" the problem down to Singular and do the work in it. |

2013-06-29 08:52:58 +0200 | answered a question | Get a matrix to display answers as decimals/floats, not fraction? 1) You can easily write matrix "multilined". By default Python joins lines if the first one contains an opening bracket/parenthesis. Hence you can easily write: 2) In order to display matrix entries as decimals you may convert a matrix base field to or alternatively: |

2013-06-29 05:19:40 +0200 | commented answer | Outputing lists without brackets in SageTeX Thanks for your reply. It indeed solves the problem in two example cases I presented, but... still I sometimes need yet another delimiters around the sage's output (e.g $\langle$ or $\langle\langle$...) |

2013-06-27 08:37:27 +0200 | asked a question | Outputing lists without brackets in SageTeX Hi, how can I output a list in SageTeX without it being enclosed in brackets? Consider for example: and in the text produces $A = \{ \left[1, 2, 4\right] \}$ instead of $\{ 1,2,4 \}$. Or a more realistic example: and know somewhere in the text I want to put but the result is: $\{ \left[x^{2} + 1, y\right] \}$ rather then expected $\{ x^{2} + 1, y \}$ |

2013-02-14 12:02:14 +0200 | asked a question | Hyperbolic forms over Qp(2) Is this a bug in Sage or am I doing something wrong: The answer should be clearly |

2012-12-23 10:24:53 +0200 | asked a question | is_square in p-adics I need to find whether a given (often somewhat complicated) dyadic field contains $i$. I tried to use Consider the following (very simplified) example:
As far as good - the answer is
And... I'm getting an error message:
Is this a Sage bug or I'm doing something wrong? |

2012-12-13 04:04:43 +0200 | answered a question | Normalization (integral closure) I believe this can be easily computed with Macaulay-2, as documented here: http://www.math.uiuc.edu/Macaulay2/do... (BTW, this is yet another reason to integrate Sage with Macaulay by default, not only as a optional package.) |
