Tame Automorphisms of ℂ³ with Multidegree of the Form (p₁,p₂,d₃)

Bulletin of the Polish Academy of Sciences. Mathematics

Similarity:

Let d₃ ≥ p₂ > p₁ ≥ 3 be integers such that p₁,p₂ are prime numbers. We show that the sequence (p₁,p₂,d₃) is the multidegree of some tame automorphism of ℂ³ if and only if d₃ ∈ p₁ℕ + p₂ℕ, i.e. if and only if d₃ is a linear combination of p₁ and p₂ with coefficients in ℕ.

On the automorphism group of the countable dense circular order

J. K. Truss (2009)

Fundamenta Mathematicae

Similarity:

Let (C,R) be the countable dense circular ordering, and G its automorphism group. It is shown that certain properties of group elements are first order definable in G, and these results are used to reconstruct C inside G, and to demonstrate that its outer automorphism group has order 2. Similar statements hold for the completion C̅.
