For a free presentation 0 → R → F → G → 0 of a Leibniz algebra G, the Baer invariant \cal M\sf Lie(G) = \fracR ∩ [F, F]Lie[F, R]Lie is called the Schur multiplier of G relative to the Liezation functor or Schur Lie-multiplier. For a two-sided ideal N of a Leibniz algebra G, we construct a four-term exact sequence relating the Schur Lie-multiplier of G and G/N, which is applied to study and characterize Lie-nilpotency, Lie-stem covers and Lie-capability of Leibniz algebras.
