[sage-combinat-devel] how to cure TestSuite failures involving Homs

2014-03-16 Thread Mark Shimozono
Is there an easy way to get rid of the following TestSuite failures? Or does it require an overhaul of how sage handles morphisms? I understand why the first two tests fail. --Mark sage: F=CombinatorialFreeModule(ZZ,[1]) sage: def on_basis(x): ... return x

[sage-devel] solving numerically polynomial equations

Hi, Going through the web I just discovered a new software called Bertini [1]. One of its capability is to get arbitrary precision numerical solutions of a set of polynomial equations. I do not think that Sage is already able to do that, right ? Does any developer of Bertini on that list ? Does
