On Universal Equivalence of Partially Commutative Metabelian Lie Algebras
Evgeny Poroshenko
In this paper, we consider partially commutative metabelian Lie algebras whose defining graphs are cycles. We show that such algebras are universally equivalent iff the correspondi…

Universal equivalence of partially commutative metabelian Lie algebras
Evgeny Poroshenko, Evgeny Timoshenko
In this paper, we find a criterium for universal equivalence of partially commutative Lie algebras whose defining graphs are trees. Besides, we obtain bases for partially commutati…
