OK, I found the problem! When trying to compile 8.9 I got a more explicit error message (which I since then "lost" by compiling again) when it also failed due to openblas. The problem was using export MAKE="make -j4 -l5.5" as suggested in the README.md file. The `-l5.5` parameter was the pro

[sage-support] Lie algebra morphism, mutable matrices, basis not defined

2020-01-03 Thread Samuel Lelièvre
Dear sage-support, At Sage Days 106 we are trying to learn some of the Lie algebra functionality in SageMath and have two small questions regarding Lie algebra morphisms. We define the Lie algebra sl_2(QQ) in two ways as follows: sage: sl2 = lie_algebras.sl(QQ, 2, representation='matrix')
