Hello, I have the following problem on my machine: - connect to a new secure Sage notebook - log in - log out - log in - now it is not possible to log out, I am just thrown to the home page (and it does work, i.e. I still have access to all the worksheets). Clearing the history of the browser

P.S. I tried removing the cookie of the notebook site - this disconnects me from the notebook server, but after the first login I cannot logout anymore. -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to

I am having the same issue with Ubuntu 9.10 64-bit running in a VirtualBox. I've tried installing some packages (although not all) appearing in the package manager for openssl, but nothing has changed. Andrey On Nov 12, 12:53 am, William Stein wst...@gmail.com wrote: On Wed, Nov 11, 2009 at

[sage-support] Automatic coercion between polynomial rings

Is the following behaviour a bug or an intended one? sage: R1 = PolynomialRing(QQ, x, y) sage: R2 = PolynomialRing(QQ, y, x) sage: R3 = PolynomialRing(QQ, a1, a2) sage: R1.inject_variables() Defining x, y sage: print R1(R3(R2(x))), R1(R3(R2(y))) y x Personally I don't think that R3 has any

[sage-support] What is the difference between double and single quotes?

Hello, I was sure there is no difference in Python and Sage. However, when I try to return I_0 in _latex_ function of my class, it typesets as I_0, because somehow it gets wrapped into \text{I\_0}. When I change the return value to 'I_0' everything works as expected. Why is it so and are there

This is a known bug: http://trac.sagemath.org/sage_trac/ticket/2120 I hope it gets looked at again at Sage Days next week (which is a week of developers fixing bugs). I will be really glad if this happens! Andrey --~--~-~--~~~---~--~~ To post to this

[sage-support] Fractional powers for polynomial variables

Hello, I need to substitute some variable in a polynomial ring with a fractional power of another one. I know that the result still will be a polynomial, however I have discovered the following behaviour (v. 3.0.5 on sage.math): sage: pr = PolynomialRing(QQ, u,v) sage: pr.injvar() Defining u, v

[sage-support] Normalizing symbolic polynomial

Hello, I have a symbolic expression which is a polynomial in t and t^(-1). I want to multiply it by some power of t so that it is a polynomial of t. How can I determine this power? Coefficients are some symbolic expressions in other variables, e.g. sqrt(a)*t+1/t^2. Thank you, Andrey

[sage-support] Mixing polynomial rings

Hello, What is wrong with the code below and how to fix it? I have a function that produces a polynomial in t. Then I want to plug in u/v in another function. The code works if I replace QQ by ZZ at least for the first ring, but rationals seem to be much faster. Thank you! Andrey Rt.t =

[sage-support] Time limit for computation

Is there any way to automatically terminate the current computation if it takes longer than given amount of time (say, a minute)? I want it to be inside a loop that will stop some iterations and continue, if they are taking too long. Thank you, Andrey
