Résumé

When $1 < p < \infty$ and $p \neq 2$ the $p$ -harmonic measure on the boundary of the half plane $ℝ_{+}^{2}$ is not additive on null sets. In fact, there are finitely many sets $E_{1}$ , $E_{2}$ ,..., $E_{κ}$ in $ℝ$ , of $p$ -harmonic measure zero, such that $E_{1} \cup E_{2} \cup . . . \cup E_{κ} = ℝ$ .
