A note on k[z]-automorphisms in two variables

Eric Edo, Arno van den Essen, Stefan Maubach

We prove that for a polynomial $f \in k [x, y, z]$ equivalent are: (1) $f$ is a $k [z]$ -coordinate of $k [z] [x, y]$ , and (2) $k [x, y, z] / (f) ≅ k^{[2]}$ and $f (x, y, a)$ is a coordinate in $…

\C-flows A^z of linear maps A expressed in terms of A^{-1},A^{-2},...,A^{-n} and analytic functions of z

Stefan Maubach

Suppose A\in GL_n(\C) has a relation A^p=c_{p-1}A^{p-1}+.... + c_1 A+ c_0I where the c_i in \C. This article describes how to construct analytic functions c_i(z) such that A^z=c_{p…
