Lower Central Series
摘要
Throughout this sectionLdenotes an enriched Lie algebra, with quotient maps \(\rho _\alpha : L\to L_\alpha \) . The lower central series \(L^{(n)}\) ofLis the analog for enriched Lie algebras of the usual lower central series \(L^n\) . The closed ideal \(L^{(n)}\) is the closure of the ideal \(L^n\) .
