I read in mark wildon book "introduction to lie algebras"
"Let F be any field. Up to isomorphism there is a unique two-dimensional nonabelian
Lie algebra over F. This Lie algebra has a basis {x, y} such that its Lie
bracket is described by [x, y] = x"
and I'm curious,
How can i proof with this bracket [x,y] = x, satisfies axioms of Lie algebra such that
[a,a] = 0 for $a \in L$
and satisfies jacoby identity
cause we only know about bracket of basis vector for L
