Later on I no longer need `f` to be that expression. I just need it to be a variable. I know in PARI we have the function `kill(f)`. I tried that on Sage but it did not work. Can I kill a variable that I have defined earlier on Sage.ShaMon, 19 Sep 2016 03:02:01 -0500http://ask.sagemath.org/question/34855/Killing formhttp://ask.sagemath.org/question/10442/killing-form/Hi,
is there a simple possibility to calculate the Killing form in some standard matrix Lie-Algebras like $\mathfrak{so}(n,\mathbb{R})$?
Thanks in advance for your answers!twchFri, 16 Aug 2013 11:13:38 -0500http://ask.sagemath.org/question/10442/
