So, we now know that in any representation of a semisimple Lie algebra ${\mathfrak{g}}$, the semisimple elements act by diagonalizable operators. Now if we were given an abelian subalgebra ${\mathfrak{h} \subset \mathfrak{g}}$ whose elements were semisimple, then every simple representation ${V}$ of ${\mathfrak{g}}$ wo... | open-web-math/open-web-math | |

2(a + bi) - 3 ( a - bi) = -7 + 2i
-a + 5bi = -7 + 2i
a = 7
5bi = 2i
5b = 2
b = 2/5
z = 7 + (2/5) i Jun 22, 2021 | HuggingFaceTB/finemath | |
