Title: Statistics of $K$-groups modulo $p$ for the ring of integers of a varying quadratic number field,
Abstract: For each odd prime $p$, we conjecture the distribution of the $p$-torsion
subgroup of $K_{2n}(\mathcal{O}_F)$ as $F$ ranges over real quadratic fields,
or over imaginary quadratic fields. We then prove that the average size of the
$3$-torsion subgroup of $K_{2n}(\mathcal{O}_F)$ is as predicted by this
conjecture.
