I've posted a patch that I think will be of particular interest to
sage-algebra, especially any of you interested in sages ability to
work with modules. The patch gives sage the ability to create
representations of quivers. Sage will treat these representations as
modules, specifically you can create elements, homomorphisms, and
homomorphism spaces. There's lots of functionality up to and
including the ability to create the projective cover and compute
Auslander-Rieten translations of any finite dimensional module.

If any of that sounds interesting to you then please review:

Cool! I am currently working on the computation of ext algebras of
finite-dimensional quotients of quiver algebras. So, I'll certainly
have a look at your patch.

Cheers,
Simon

Hi,

I would like to start developing in sage but I have no idea where to start. Since I have an homological algebra background, this patch seems a good place. Unfortunately I am really lost in sage's internal behavior. I would appreciate any advice.

Best regards,

Quimey Vivas

PS: I was playing a little bit with the patch and it seems that it is not too far from being able to compute Ext vector spaces. Is anybody working on that?
