[sage-support] Cubic root in a finite field
Hi! I have the following: p=371 Fp2=GF(p^2, 'b') and I want to compute the cubic root of 344694*b + 1653339. How can I do it? Because when I write (344694*b + 1653339)^(1/3) it gives me as result 1, and the same for every element that I consider in Fp2, or for every exponent 1/n. -- You received this message because you are subscribed to the Google Groups sage-support group.

Re: [sage-support] legend
Hi,
Sorry I mistaken : Your suggestion does work but apparently some
commands don't work.
I am trying further...
Thanks

Hi,
I do a plot with **params which is quiete usefull to have it as a
compact style.
After googling a lot I was trying to see if one can do the same with
**legend ? or other keyword ?
I didn't find any answer, is it possible ?
it would be easier to put all in a command ?
The same syntax should work:
legend_opts = { 'back_color': 'white', 'shadow': True }
p.set_legend_options(**legend_opts)

Here is one way: sage: p=371 sage: Fp2.b=GF(p^2) sage: a = 344694*b + 1653339 Now either sage: x = polygen(Fp2) sage: (x^3-a).roots(multiplicities=False) [401927*b + 661235, 259308*b + 3298074, 3038766*b + 3440693] or just sage: a.nth_root(3) 259308*b + 3298074 sage: a.nth_root(3,all=True) [259308*b + 3298074, 3038766*b + 3440693, 401927*b + 661235] Since the field contains the 3rd roots of unity there are three cube roots (if any). I don't exactly know what the ^(1/3) promises, since Sage calls pari and I have not looked up the pari documentation. Since your output was 1 it looks suspiciously as if the 1/3 was rounded before exponentiation. And since 1 is certainly not one of the cube roots of a, I think you have found a bug!

Hi Thanks for reporting this. Many of the Depends: fields in sagemath need to be updated. I will do so over the coming month or two. In the meantime, simply to satisfy the dependency, add the ffmpeg from saucy.-updates, which seems to be the last one. http://packages.ubuntu.com/search?keywords=ffmpeg So I suggest this (easily disabled later). sudo -i cat /etc/apt/sources.list.d/saucy-updates.list EOF # Only for ffmpeg, to satisfy lingering sagemath-upstream-binary dependency deb http://archive.ubuntu.com/ubuntu/ saucy-updates main EOF apt-get update apt-get install sagemath-upstream-binary To remove later, after sagemath-upstream-binary is updated, (by me, and by you from the PPA) do sudo apt-get purge ffmpeg sudo rm /etc/apt/sources.list.d/saucy-updates.list sudo apt-get update sudo apt-get autoremove # check output and say yes if acceptable.

Re: [sage-support] The ubuntu ppa need ffmpeg but it is not the name in ubuntu 14.04
Hi Emmanuel, Thanks for that. So I understand that without the ffmpeg PPA my solution might work? I have mailed sage-devel to sort out the dependencies, and I can perhaps release an intermediate new version which is the same version of sagemath but with new dependencies.

I'm less strict about absolute dependencies since the purpose of the PPA is to make it easy for people, easier than any manual installation, and some Recommends: might become Depends: in this situation. However NONE of the dependencies seem to be real dependencies to run sage, but for some functionality, e.g. openssl: run secure mode imagemagick, some commands in sage not my dependency, but a browser to run the notebook. I want to have people not worry about these things. All functionality should just work. But we should also keep the Debian Way in mind, of course.

Looks like it, yes: http://askubuntu.com/questions/432542/is-ffmpeg-missing-from-the-official-repositories-in-14-04 I'm suprised at the lack of an ffmpeg-compat package though... and a virtual package ffmpeg... anyway, I will look at updating the PPA soon. PS. I've also updated my sagemath buildslave from precise to trusty. Soon trusty binaries will appear, and that will be what I will repackage with appropriate dependencies and recommendations.

I've searched sage-support, ask sage and trac sage, but couldn't find any
similar issue.
Checking the source code I coded the following workaround within the cell (

Is this a bug in the method show() from the Tachyon class?
Thanks in advance,

[sage-support] Random Primitive
Hi everybody. There is a procedure or library in SAGE that allows finding a random primitive element on a finite field? -- You received this message because you are subscribed to the Google Groups sage-support group.

Re: [sage-support] The ubuntu ppa need ffmpeg but it is not the name in ubuntu 14.04
Thank you for your reply and hard work, I love sage. Thanks again. 在 2014年4月19日星期六UTC+8下午9时07分18秒，Jan Groenewald写道： Hi Thanks for reporting this. Many of the Depends: fields in sagemath need to be updated. I will do so over the coming month or two. In the meantime, simply to satisfy the dependency, add the ffmpeg from saucy.-updates, which seems to be the last one. http://packages.ubuntu.com/search?keywords=ffmpeg So I suggest this (easily disabled later). sudo -i cat /etc/apt/sources.list.d/saucy-updates.list EOF # Only for ffmpeg, to satisfy lingering sagemath-upstream-binary dependency deb http://archive.ubuntu.com/ubuntu/ saucy-updates main EOF apt-get update apt-get install sagemath-upstream-binary To remove later, after sagemath-upstream-binary is updated, (by me, and by you from the PPA) do sudo apt-get purge ffmpeg sudo rm /etc/apt/sources.list.d/saucy-updates.list sudo apt-get update sudo apt-get autoremove # check output and say yes if acceptable.

i know that but this function only give you one generator, always the same but i want a random generator of a multiplicate group of a finite field. -- You received this message because you are subscribed to the Google Groups sage-support group.

I like your screen name. Share that Sage!
I can't find this display_image thing anywhere in the Sage source, and
perhaps this is a Sage cell specific thing so that Tachyon things work in
that context (it's neither the command line nor the notebook server, so
some custom code may be necessary). I'm not sure where you found the
display_image, though; even in the Sage cell patches to Sage [1] ... but
presumably this is a Sage cell specific thing, given their custom code, and
I encourage you to report it there [2]. Thanks for the report!
