2011-05-05 09:24:53 -0500 | asked a question | How can I construct modules as quotient algebras? I would like to do the following: given a field k and an ideal I of A = k[x1,...,x_n], I would like to construct the k-module A/I and, when A/I is finite as a k-module, compute its rank. Is this possible in Sage? |

2011-04-18 12:58:19 -0500 | asked a question | Matrix of Frobenius action on the de Rham cohomology of a curve. I'd like to be able to compute the matrix of Frobenius action on the de Rham cohomology of a curve in characteristic p. Has this been implemented in SAGE? I couldn't find anything in the documentation, or googling for papers which compute this. Also, computation of the Hasse Witt Matrix has been implemented. |

2011-02-26 07:37:04 -0500 | marked best answer | How do I create subsets of sets? Here is one solution: For more documentation on this, look for list comprehensions in your favorite Python documentation. |

2011-02-26 07:17:51 -0500 | asked a question | How do I create subsets of sets? How do I create, for example, the set of all primes less than 100 which are congruent to 1 mod 6? In Magma, I would do something like this: After 25 minutes of searching the Sage documentation, googling, and trying things at random, I can't figure out how to make such a construction in Sage. (I'm not so interested in this particular set, but rather how to do constructions like this in general [e.g., the subset of all matricies whose given minor has a certain rank, etc.). |

2011-01-25 16:05:37 -0500 | asked a question | How do I nest functions? The following code returns an error, while the code works fine. Is there a way to do this on one line? (Note: I don't particularly care about this with elliptic curves, I'd just like to be able to do things like this in one line. In other words, I'm not looking for a mathematical answer. Also, I'm asking for something different than, say, this .) |
