Аннотация: Let Bn be a polynomial algebra of n variables over a field F. Considering a free associative algebra An of rank n over F as a polynomial algebra of noncommuting variables, we choose the ideal R of all polynomials with a zero absolute term in Bn and An. The well-known concept of wild automorphisms of the algebras An and Bn is transfПоказать полностьюerred to R; the study of wild automorphisms is reduced to monic automorphisms of the algebra R, i.e., those identical on each factor Rk/Rk+1. In particular, this enables us to study the properties of the known Nagata and Anik automorphisms in detail. For n = 3 we investigate the hypothesis that the Anik automorphism is tame modulo Rk for every given integer k 1. © 2015, Springer Science+Business Media New York.
