Does anybody have any GSoC projects to add to
http://wiki.sagemath.org/GSoC/2015
There were basically zero that involved actual mathematics, so I've
added two. One is relevant for quaternion algebras and another for
modular forms.
Hey people -- you could use this to support a frickin' grad
Thanks a lot to both of you. The trick with import sage.all worked nicely.
Regarding the existing implementation of unordered rooted trees, it looks
very much like what I need. Some of the programming is a bit over my head,
so I don't think I'll be able to finish the implementation. Do you know
Hi,
from what I remember, it was finished but depended on this one:
http://trac.sagemath.org/ticket/10194
Which is also almost finished but still not...
These two tickets come from the old combinat queue (when Sage wasn't on git
yet) and were shared among combinat people without being merged,
Hi,
What is the recommended way to implement a parent that needs a fast
element constructor but otherwise can be expected not to be queried too
often once the coercion maps involving it are set up ? (I would like
MyParent(obj) to have as little overhead as possible, not just
coercions.)

Hi,
I don't know about your import error. But I just wanted to say than
unordered trees were implemented a while ago but never finished...
Here's the ticket:
http://trac.sagemath.org/ticket/11529
I'm not saying you should use those, maybe it's better to start from
scratch, but it's always good

Hello,
And it fact, something like Butcher series is also waiting in ticket #15635
This depends of course on #11529, which is currently blocked by
ticket #10194
I have tried to work on #10194, but the author has not answered my
questions so far.
If somebody in his university could ask him

I tend to add it to OUTPUT, like
OUTPUT:
Returns the frob of x and y. If ``self`` is not in the range from 3 to 7
then a ``ValueError`` is raised.
