Hi all,
I was trying to run a GAP session inside sage, with gap_console() and
when the Smallgroups library is needed, I obtain an error:
Error, the Small Groups library is required but not installed called

Hi Kiran,
Adding good Lie algebra support to Sage has been something on my list
for awhile. I just made it out here to Berkeley and am going to be
here all semester for the program at MSRI. I was that you were

Dear Peter,
I must confess, with apologies, that I am an expert in neither
statistics nor SAGE, and that I have not fully understood your code
(or, for that matter, "New Age Solitaire"). But I suspect there is
an error in your computation showing that "seven shuffles are
insufficient." The clai

I just looked at the GAP docs, and I don't quite see how to do what I

it's possible.
What I do know is that Magma has some of this functionality,

I'd like to set up a sage notebook for my class to use. At the AMS
meetings, William mentioned that the easiest way to do this was to use
the vmware appliance to run the notebook (even if I plan to run the
appliance under linux). I presume the reasons have to do with security.

I am facing a similar problem, and I am not sure how to handle it. It
would be nice to be able to create/destroy accounts for a notebook on
the command line. Eventually I would like to provide sage servers for
hundreds of students, and it has to be easier to administrate than it
is currently.

Actually, there is: there is a noGlobal.js plugin that you can use to
disable the global mode if you are using it in a context where global
mode doesn't work. I don't know how sage loads jsMath, b

I think Sage doesn't include any nontrivial Lie functionality.

Does SAGE currently include any functionality for manipulating Lie
algebras? (I only need reductive Lie algebras, because I'm using them
to study compact Lie groups.) For instance, I'd like to be able to
manipulate irreducibles (encoded by their highest weights), so that I
can form a tensor produc

Excellent work tracking that down, which I would have never noticed.
sage: preparse('f(x) = x')
'_=var("x");f=symbolic_expression(x).function(x)'
sage: preparse('f(x) =+x')
'f(x) =+x'
sage: preparse('f(x) =-x')
'

The problem is surely that the pieces f1a etc are just Python
lambda-functions, yet the integral() method is being called on each of
these in the line
return sum([funcs[i].integral(x,invs[i][0],invs[i][1]) for i in range(n)])
so the problem arises since you are asking to integrate each funcs[i]
bu
At the moment,
(a) "piecewise" is only set up for piecewise polynomials,
(b) the "integrate" command is "integral".
So, for your function (which is piecewise polynomial), this should
work:
sage: f1a = lambda x: -x+1; f1b = lambda x: x+1
sage: f2a = lambda x : -(x - 2) - 1; f2b = lambda x : (x - 2
Thank you very much for your answers,
I will continue in the proposed direction.
With best regards,
Lars Fischer
