On even $K$-groups over $p$-adic Lie extensions of global function fields

Abstract

Let $p$ be a fixed prime number, and $F$ a global function field of characteristic not equal to $p$. In this paper, we shall study the growth of the Sylow $p$-subgroups of the even $K$-groups in a $p$-adic Lie extension of $F$, where the $p$-adic Lie extension is assumed to contain the cyclotomic ${\mathbb{Z}}_p$-extension of $F$. We also establish a duality between the direct limit and inverse limit of the even $K$-groups.
