Abdelwahab, Hani; Calderón Martín, Antonio J.; Fernández Ouaridi, Amir Central extensions of 4-dimensional binary Lie algebras. (English) Zbl 07274818 Rocky Mt. J. Math. 50, No. 5, 1541-1559 (2020). Summary: The class of binary Lie algebras contains the one of Malcev algebras (and so the one of Lie algebras). We provide a classification of central extensions of complex non-Malcev binary Lie algebras of dimensions either \(3\) or \(4\). From here, a classification of central extensions of complex non-Lie anticommutative \(\mathfrak{CD}\)-algebras of dimensions either \(3\) or \(4\) is also given.
