Minimal varieties of algebras of exponential growth
A. Giambruno and M. Zaicev
Abstract.
The exponent of a variety of algebras over a field of characteristic
zero has been recently proved to be an integer.
Through this scale we can now classify all minimal varieties of a given
exponent and of finite basic rank.
As a consequence we describe the corresponding T-ideals of the free
algebra, and we compute the asymptotics of the related codimension
sequences.
We then verify in this setting some known conjectures.
