Abstract
Finite-dimensional Lie algebras with trivial Killing form are studied. The main properties of the Killing form are specified, a series of examples of Lie algebras with trivial or non-trivial Killing form are given. A classification of Lie algebras of dimension \(\le 5\) with trivial Killing form is given. Some results are found about the space of all Lie algebras with trivial Killing form.
