The paper introduces a general construction which associates an algebra A(\({\mathfrak L},b)\) with every pair (\({\mathfrak L},b)\), where \({\mathfrak L}\) is a Lie algebra and b is an invariant symmetric bilinear form on \({\mathfrak L}\). This construction leads to a unifying view of several well-known (associative and nonassociative) algebras.
The paper characterizes the pairs (\({\mathfrak L},b)\) which generate associative algebras A(\({\mathfrak L},b)\) and the algebras A which can be represented in the form A(\({\mathfrak L},b)\).
