Witt's formula for restricted Lie algebras.
The author computes the Hilbert-Poincaré series of a free restricted Lie algebra and obtains a Witt formula for the dimensions of its homogeneous components. In an earlier paper [in: Formal power series and algebraic combinatorics, Moscow, 2000, Berlin: Springer, 543--551 (2000; Zbl 0993.17005)] the author dealt with the case of free Lie superalgebras.
