Schreier's formula for free Lie algebras
The author establishes an analogue of Schreier's formula for subalgebras of free Lie algebras in terms of formal power series. Similar formulae are given for free Lie \(p\)-algebras and superalgebras. As an application the author computes the Hilbert-Poincaré series for some finitely generated solvable Lie algebras and groups.
