[sage-support] Testing equality for elements in a quotient of a multivariate polynomial ring

2017-07-14 Thread Keir Lockridge
I'm experiencing what seems to me to be inconsistent behavior in testing equality for elements of a quotient ring. In the code below, the first print statement gives "False", but the second one gives "True". Am I doing something wrong? A = Integers(4) R. = PolynomialRing(A,2) I = R.ideal(x^2 +

2017-07-14 Thread Keir Lockridge
When I execute the following block of code in a Sage worksheet (I did this in a .sagews file on cocalc.com, kernel 7.6), I get unexpected behavior from the last pretty_print statement (the LaTeX doesn't render at all). A = GF(2) R. = PolynomialRing(A,1) I = R.ideal(x^5 - 1) Q. = R.quotient_ring(

Hi all, I have a working installation of the Sage notebook server on a machine running RHEL, with ssl enabled (I can connect via https and I'm running the notebook with secure=True). I just built 7.2 (with ssl support, per the installation instructions, as I did with 6.5) and now I'm getting th

[sage-support] LaTeX rendering problem in a local installation of the sage notebook server

2014-06-13 Thread Keir Lockridge
Hi, I have Sage v6.2 installed 'in the cloud' (Amazon). The OS is RHEL. I have used Sage for a couple of years without incident, but I am suddenly having a problem with LaTeX rendering in the notebook. When I enclose a formula in double dollar signs, it renders just fine as a centered equation.
