[sage-devel] Re: Poll: Making sage-mode a standard package
[X] Make it standard at some point in the near future Mainly because I think everybody should use emacs as their operating system. it will save their time and the money they spend on buying fancey computers. Also Nicolas is very cool so I wanted to support his point ;) That's said, I found couple of bugs in it when I use it with emacs 24, for example you can only run sage-build from a window with inferior-sage-mode (subproblem of what we discussed before probably you need to add that hook thingi to the sage-build as well), also autocomplete and keyword?? take ages to work. It also hijacks python files no matter if there's a python interpretor open or not (I wrote a fix for this one). Though, it's unstable emacs 24. But if by the time it gets released, sage-mode is not standard, it's less probable that somebody cares about these bugs as Benjamin said. בתאריך יום רביעי, 30 במאי 2012 09:27:05 UTC-6, מאת David Kohel: [X ] Make it standard at some point in the near future. Argument: Sage includes many interfaces to standard software. This includes software that the majority users will never use in their lifetimes, e.g. the big M's (unless at a mathematics department or institute where there exists a license) and numerous open source software libraries and systems. Emacs is a standard open source tool, and an interface (albeit from emacs to sage) seems reasonable. I also thought that this was standard in the sense that it was one file which one could find (like sagetex.sty) in the sage distribution. I would like to find it there if I need to update my system. --David On May 30, 7:44 am, Ivan Andrus darthand...@gmail.com wrote: On May 25, 2012, at 11:24 PM, Ivan Andrus wrote: Dear all sage and emacs (or not) users, Since I've been working on sage-mode a bit recently I thought I would look at trac and try to fix any sage-mode related bugs there.

[sage-devel] Re: genus() for Function Fields
Hi Maarten, I see this in Florian Hess's codes ### # Genus GffDifferentDeg := function(K) local of, oi, df, di; of := GffOrderMaxFinite(K); oi := GffOrderMaxInfty(K); df := GffOrderDisc(of); di := GffOrderDisc(oi); return (PolyDeg(df) + InftyVal(di))/GffDimExactConstField(K); end; #GffGenus := function(K) # local d, dim, n; # # n := GffDeg(K); # dim := 1; # d := GffDifferentDeg(K); # # return d/2 - n/dim + 1; #end; Which basically uses Riemann-Hurwitz to compute the Genus. But I don't think it's the fastest way to do it. I think analyzing the singularities is faster than analyzing the ramification. (It might be the reason that he commented GffGenus out) Anyway, I sent him an email and asked him about his opinion. First: I couldn't find the implementation for GffOrde... functions.

I think it is essential (speaking priority) to have a parallel to Magam RationalExtensionRepresentation(F) : FldFunG - FldFun The function field F represented as an extension of a rational function field.

[sage-devel] solve_right's behavior on singular matrices
Hi there, I was looking at solve_right. And as much as I understand if the system has infinitely many solutions it just generates a random solution (with free vars = 0). Doesn't it make more sense that it gives back a matrix : [C0 C1 C2 ..] such that X = C0 + C1*t1 + C2*t2 + ... be a solution to the system. I mean who needs a random solution? On the other hand, as much as I dug into to the documents, sage doesn't have a function that take matrix A and columnar vector B and gives the parametric solution for singular systems. I know it's easy to compute using the echelon_form but considering how often it is used, it deserves a dedicated function. And solve_right seems the right function. Also, I saw that 'solve' uses Maxima to solve a linear system. But entering the equations in solve isn't as easy as entering the coefficient matrix. Should I start a ticket on solve_right to behave differently in the case of singular matrices? It will be somehow backward compatible as the first column is a solution to the system. Or should we give it a different name.

Hi Julian, Thank you very much for your reply. If you put the isomorphisms codes available, it will probably helps me a lot. I don't know about the iterated extensions, but when I wanted to write GHS attack related code for my Masters back in 2008 I started with sage and I used the field of fraction of the coordinate ring approach. For that I needed to build a tower of degree 2 extensions, but sage told me that after I extended my rational field, I reached the end of the road, basically I couldn't extend a non rational function field. That was the time that I was sold to Magma. And thank you for telling me about IRC. I'll probably bug you pretty soon there.

[sage-devel] Re: The status of function field development
Hi Maarten, Thank you for the link. It was the thing I was looking for. I have read Hess's paper on his algorithm for computing basis for Riemann- Roch space . I'm pretty happy to start working on it , once I went through your code and see what we have available at hand. Also for my research I was thinking about implementing some of the algorithms when the minimal polynomial or the curve equation is given parametrically. This is something that Maple is good at it but I don't think Magma support anything of that kind. For example I once I roughly went through the algorithms in RR paper of Hess and I saw no serious obstacle in all necessary algorithms if the curve equation is given parametrically (for example you can still do ideal reduction, etc basically if you don't solve non-linear equation then probably it should work). Anyways, I'm going to delve into the patch and I'll get back to you with question. Cheers, Syd P.S. I think I reported the thread by mistake as offensive or something and I can't undo what I did.

Very nice that you want to get started implementing more function field stuff in sage! The best overview of what we want to get done is probably on [1]. A lot of the more basic things over there have already been implemented, so now it is time to start on the more interesting algorithms (divisor reduction, and the computation of riemann-roch spaces and picard groups). These things can already be computed in magma, but not yet in sage sadly enough. A good point to start reading about the different algorithms wich still need to get implemented are the paper and slides of Florian Hess on [1]. [1]http://wiki.sagemath.org/daysff/curves ps.
