Determining the Lie Algebra of a Vector Space

Click For Summary
SUMMARY

The discussion clarifies that a Lie algebra over a field K is defined as a K-vector space equipped with a K-bilinear operation known as the Lie bracket. It emphasizes that there is no singular Lie algebra associated with a vector space; rather, an infinite number of Lie algebras can be constructed from any given vector space. The example of the horizontal space illustrates this concept, reinforcing the idea that the structure of Lie algebras is diverse and not unique.

PREREQUISITES
  • Understanding of K-vector spaces
  • Familiarity with K-bilinear operations
  • Knowledge of Lie brackets

hi friends !
it is well known that a Lie algebra over K is a K-vector space g equipped
of a K-bilinear, called Lie bracket. I ask how can we determines the Lie algebra of any vector space then? For example we try the Lie algebra of horizontal space.

You seem to have the idea that there is such a thing as "the" Lie Algebra of a vector space. That's not true. There exist an infinite number of Lie Algebras for a given vector space.
