Growth of codimensions of metabelian algebras
M. V. Zaicev Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract:
We consider numerical invariants of identities of nonassociative algebras. We prove that codimension sequence of any finitely generated metabelian algebra has exponentially bounded codimension growth. It is shown that the upper PI-exponent increases at most to 1 after adjoining an external unit. For two-step left-nilpotent algebras it is proved that the lower PI-exponent increases at least to 1.
Key words:
identities, codimensions, metabelian algebras, PI-exponent.
