And here I got the following error: raise IOError('did not find file %r to load or attach' % filename) IOError: did not find file './file2.sage' to load or attach I hope somebody has an answer to this kind of problems. |

2018-02-18 15:15:17 +0200 | asked a question | Pullback of ideals Hi. I have the the following question and I hope that somebody of you has a good idea for the implementation and an explanation of the error. Offset:
Question: How to compute the pullback of IL for (general) fractional ideals of K? My approach:
Such vectors v are the vectors in the preimage of W'. EXAMPLE 1: EXAMPLE 2 (and the first problem, loosing the denominator) My improvement approach: Now EXAMPLE 2 returns the corresponding fractional ideal I_ BUT with an incorrect ideal I_ in EXAMPLE 1. Thanks for helping! |

2017-12-05 19:53:37 +0200 | answered a question | Morphism between Klein four group and additive abelian group or order 4 Thank you for the fast answer. C is the always the class group of a quartic/sextic CM filed and G is the corresponding abstract group "printed by sage". Yes, I assume that I have to construct the inverse image too. |
2017-12-05 11:03:14 +0200 | asked a question | Morphism between Klein four group and additive abelian group or order 4 Hi. Let's say I have an ideal class C with structure G := C2 x C2. I want now to construct a morphism phi: G --> C, s.t. phi(g1) = c1 and phi(g2) = c2. |
