Iterate extensions and relative Lubin-Tate groups
Laurent Berger 氏 (ENS de Lyon)
Iterate extensions and relative Lubin-Tate groups
[ 講演概要 ]
Let K be a p-adic field, let P(T) be a polynomial with coefficients in K, and let {$u_n$} be a sequence such that $P(u_{n+1}) = u_n$ for all n and $u_0$ belongs to K. The extension of K generated by the $u_n$ is called an iterate extension. I will discuss these extensions, show that under certain favorable conditions there is a theory of Coleman power series, and explain the relationship with relative Lubin-Tate groups.
