I do not see how that rules out clisp 2.47 - or am I just not getting what you are driving at :) Is there something else I can try?

On the Department of Mathematics and Computer Science we want to promote the computational techniques.

I am personally a user of the package and extensivly use it with high ranks elliptic curves of my own. If you could help us with obtaining some gadgets and free SAGE copies for the event I will be greatly obliged. I don't personally provide or make Sage DVD's or other gadgets.

[sage-support] Re: Dirichlet L-function
Thanks :) On 26 Apr., 02:43, Craig Citro craigci...@gmail.com wrote: Hi, The example from the reference manual p.2630 sage: lcalc.twist_values(0.5, -10, 10) [(-8, 1.10042141), (-7, 1.14658567), (-4, 0.667691457), (-3, 0.480867558), (5, 0.231750947), (8, 0.373691713)] works fine. But I need the value of L( chi_3 , 2 ). I think the problem is just one of documentation. In fact, the twist_values command calls into lcalc, and it's giving you twists by quadratic characters with *conductor* between dmin and dmax, *not* the characters of the form (d/.) with d between dmin and dmax. As it happens, the Kronecker symbol (3/.) happens to have conductor 12, not 3, which is what's causing the confusion: sage: kronecker_character(3).conductor() 12 Then this should be the value you want: sage: lcalc.twist_values(2,12,12) [(12, 0.949703126)] I'll file a trac ticket about this right now ... and a patch is up: http://trac.sagemath.org/sage_trac/ticket/5896 Anyone want to give this a quick review? -cc --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
[sage-support] Re: Slackware/Zenwalk package
Dear Michael, dear Minh, I had strongly underestimated the HD-space consumption of a sage server. (I didn't look into the reader ...) Man, it is huge! After re-partitioning my drive I ran the installer in a command line session, like Minh has tought me. It took somewhat between 15 and 18 hours. Now sage is running on that old notebook. You who developed it did a great job. (I am very impressed by that software. I am going to hold some tutorials for the kids at my german high school how to use sage and so to have fun with math. My plan is to tell them that there are only two basic commands you need to know at the beginning, that is the TAB (to complete the command you guessed might work) and after that the question mark and shift-enter to look up the usage. Yesterday I found a third and a very exciting one: search-doc. I think this one is going to shift sage far beyond the limits of maplesoft and wolfram.) Thanks a lot.

[sage-support] Re: Notebook server sluggish in 3.4
I have the same problem, where can I get version 3.2.3 ? Thanks. I'm using Windows XP and the VMWare emulator with Firefox on my AMD 64 X2 3.1GHz pc with 2Gb ram... 10min does seem a little long to calculate 2+2. On Apr 14, 10:45 am, ksk...@gmail.com ksk...@gmail.com wrote: I built 3.4 from source on two different but similar machines on our department network (both 64-bit Opterons running Fedora 10, but slightly different clock speeds). Those builds run fine in general. However, running a notebook server results in extremely poorperformance; it consistently takes ten or more seconds to add 2+2 in the notebook. Downgrading to 3.2.3 seems to fix this.

[sage-support] bug is subs_expr() ?
Hi all:
It looks like there's a tiny bug in subs_expr(): it hangs when given
the empty dictionary.
