2016-02-17 18:40:15 +0200 | commented answer | Run multiple instances of Sage Apparently you are right. I use Sage 7.0 on Debian unstable. I installed Sage unpacking the file distributed on Sage's website (for amd64). However, probably I did (by mistake) checkout another version and then checkout again versio 7.0. This might have corrupted something. I tried on another computer (same environment, but without that error with checkout) and it works. So probably it is my fault and that is the culprit. |
2016-02-17 18:36:12 +0200 | asked a question | Substitute elementary symmetric functions in a polynomial Suppose I do the following: Now I would like to substitute Does not do what I want (in fact it does not do anything). Is there a way to substitute a specific elementary polynomial? |
2016-02-17 17:34:38 +0200 | asked a question | Run multiple instances of Sage Is it possible to run multiple instances of Sage? If I try, the second one complains that Sage crashed and lets me send a bug report. But Sage did not crash, it is just that another instance is going. Is it intended? Is there any workaround? (I might use the notebook to do multiple things a time, I guess, but I really work better the the IPython console) |
2016-02-17 14:56:39 +0200 | commented question | Prevent Sage from executing symbolic computation Sure, that's a possibility, but I hoped not having to type the expression twice (my main aim was actually that of proof reading expressions in a more natural writing). Thanks anyway! |

2016-02-16 13:48:54 +0200 | asked a question | Prevent Sage from executing symbolic computation Hi. I would like to ask Sage not to perform a certain symbolic computation until I tell it to. This is because I would like first to show with (which should show the summation formula without executing it) and (which should show the result, as it actually does). Is this possible? |
