# A bound for the torsion in the $K$-theory of algebraic integers

### Christophe Soulé

## Abstract

Let $m$ be an integer bigger than one, $A$ a ring of algebraic integers, $F$ its fraction field, and $K_m (A)$ the $m$-th Quillen $K$-group of $A$. We give a (huge) explicit bound for the order of the torsion subgroup of $K_m (A)$ (up to small primes), in terms of $m$, the degree of $F$ over $\Bbb Q$, and its absolute discriminant.
