[sage-devel] Some Magma help
Hello everyone: It has become necessary to lean on Magma's extensive ability to compute with lattices (and in particular with ideal classes in definite quaternion algebras). I am trying to write some code in Magma (granting that this is an abomination) and for the life of me, I cannot figure out how to make block matrices using a bunch of 3x 3 matrices all defined over a number field. Here is the code I have. The function that I am trying to get to work is the BrandtOperator function: function representations(I, J, n) reqlat := J*invideal(I); reqnorm := n*Norm(reqlat); return Enumerate(reqlat, reqnorm, reqnorm); end function; function BrandtBlock(I, J, wt, n) assert RightOrder(I) eq RightOrder(J); eI := 1/2*#Units(LeftOrder(I)); RIJn := representations(I, J, n); phi := MatrixRepresentation(QuaternionAlgebra(RightOrder(I))); bnIJ := SymmetricPower(phi(0),wt-2); for alph in RIJn do bnIJ := bnIJ + SymmetricPower(phi(alph),wt-2); end for; return 1/eI*bnIJ; end function; function BrandtOperator(O, wt, n) Cl := RightIdealClasses(O); H := #Cl; blkr := [BrandtBlock(I, J, wt, n) : I, J in Cl]; // needs tweaking // return blkr; return BlockMatrix(blkr); end function; Also, if anyone is working on building functionality for lattices and in particular definite quaternion algebras over number field in Sage, I am willing to contribute to your project or in any case, if any one has any kind of a blueprint, I am willing to spend the next couple of months to thrash out some working code to compute spaces of automorphic forms of higher weight (just as BrandtModules do for weight 2; in this case, already, it would be desirable to work with Pizer-type orders but I am not sure if people have tried to implement these things in Sage). Thank you for your help with this! Kannappan. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

Sage does not provide graphviz, hence not the dot command. Hovever, there is the dot2tex optional package that allows Sage to use the graphviz you installed on your computer.

[sage-devel] dot in sage ?
Hi ! I'm using the Graphviz librairy to draw graph in the tools that I'm currently developping for sage, because it produces much better pictures than the default tool of Sage. But I use the program "dot" that I installed on my computer. If I'm not mistaken, Graphviz is partially included in Sage, but I was not able to use it. Do you know if there is a direct way to call the "dot" of sage from C code in sage ? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

Hi ! I'm currently working on things in sage that uses the librairy SDL2. This librairy is not part of sage if I'm not mistaken, but it is really usefull to draw efficiently and interact with the user. It's a low level and not too big C librairy, with a licence compatible with sage if I'm not mistaken. Do you think it is a good idea to include this librairy in sage ?

Do _l_action_ and _r_action_ actually work?

Re: [sage-devel] Re: Error building sage-8.4 on Ubuntu
No, but nixos doesn't follow FHS[0], so I am using linux namespaces (more precisely this[1]) to build sage in an environment where all the build dependencies are at their FHS locations. So sage is using nixos's gfortran, the namespaces are just so it can find it where it expects it. This worked before, I'm not sure if it stopped working because of a sage change or a gfortran update. I vaguely remembered reading something similar on the mailing list, so I thought I'd ask you what you think is causing this before spending more time debugging.

Re: [sage-devel] Re: Error building sage-8.4 on Ubuntu
Its a bit of a complicated case, but I'm not using anaconda. I'm using nixos and a special build environment that uses linux namespaces to make sure all the dependencies are in the location sage expects them. I'm using that to build sage-the-distribution when testing because that won't build natively on nixos. Am Dienstag, 30.

I have a strange bug with NumberField: when I do sage: pi = x^7 - 2*x^6 + x^3 - 2*x^2 + 2*x - 1 sage: b = pi.roots(ring=QQbar)[3][0] sage: pi = b.minpoly() sage: K = NumberField(pi, 'b', embedding=b) it works well. But if I execute it a second time, then it never terminates! Do you have a explanation and a correction to this problem ? How strange. The first 3 lines are fine the second time. So is the number field construction when you leave out the embedding. When a number field is constructed it is cached so that a new construction returns the same object, and not a copy, where possible. In your case that means checking that the embeddings are the same, which means checking that two elements of QQbar are the same. That can be expensive. If you do b1 = pi.roots(ring=QQbar)[3][0] b2 = pi.roots(ring=QQbar)[3][0] and then b1==b2 it also takes ages. I cannot remember the algorithm here but it does not look optimal; it may be working effectively in a field of degree 7*6 or possibly 7!. I note that d=b1-b2 d==0 yields True immediately.

[sage-devel] sage Python3 build: sagenb problem
I tried to build Sage with Python3 via
make configure
./configure --with-python=3
make build
(fresh clone of 8.5.beta1)
as announced on https://wiki.sagemath.org/Python3-compatible%20code
but it failed building its docs. From what I read, building the docs
does still not work (part of the log below). My question is, how to
compile it "correctly"?
FYI, I do not recall what I did about two month ago (probably the same),
but it was "easy" to compile without any errors.
Best wishes
Daniel
