Some Stably Tame Polynomial Automorphisms
We study the structure of length three polynomial automorphisms of R[X, Y ] when R is a UFD. These results are used to prove that if SLm(R[X1, X2, . . . , Xn]) = Em(R[X1, X2, . . . , Xn]) for all n,≥ 0 and for all m ≥ 3 then all length three polynomial automorphisms of R[X, Y ] are stably tame. 1. Introducton Unless otherwise specified R will be a commutative ring with 1 and R = R[X ] = R[X1, ....
متن کاملThe Tame and the Wild Automorphisms of Polynomial Rings in Three Variables
Let C = F [x1, x2, . . . , xn] be the polynomial ring in the variables x1, x2, . . . , xn over a field F , and let AutC be the group of automorphisms of C as an algebra over F . An automorphism τ ∈ AutC is called elementary if it has a form τ : (x1, . . . , xi−1, xi, xi+1, . . . , xn) 7→ (x1, . . . , xi−1, αxi + f, xi+1, . . . , xn), where 0 6= α ∈ F, f ∈ F [x1, . . . , xi−1, xi+1, . . . , xn]....
متن کاملOn Permutations Induced by Tame Automorphisms over Finite Fields
The present paper deals with permutations induced by tame automorphisms over finite fields. The first main result is a formula for determining the sign of the permutation induced by a given elementary automorphism over a finite field. The second main result is a formula for determining the sign of the permutation induced by a given affine automorphism over a finite field. We also give a combini...
متن کاملIsometry and automorphisms of constant dimension codes
We define linear and semilinear isometry for general subspace codes, used for random network coding. Furthermore, some results on isometry classes and automorphism groups of known constant dimension code constructions are derived.
متن کاملFiltrations, hyperbolicity and dimension for polynomial automorphisms
In this paper we study the dynamics of regular polynomial automorphisms of C. These maps provide a natural generalization of complex Hénon maps in C to higher dimensions. For a given regular polynomial automorphism f we construct a filtration in C which has particular escape properties for the orbits of f . In the case when f is hyperbolic we obtain a complete description of its orbits. In the ...
