Abstract:
The paper studies the additive structure of the algebra F(7), i.e., a relatively free associative countably generated algebra with the identity [x1,…,x7]=0 over an infinite field of characteristic ≠2,3. First, the space of proper multilinear polynomials in this algebra is investigated. As an application, estimates for the codimensions cn=dimF(7)n are obtained, where F(7)n stands for the subspace of multilinear polynomials of degree n in the algebra F(7).
