Removable Sets for H\"older Continuous p(x)-Harmonic Functions
  We establish that a closed set $E$ is removable for $C^{0,\alpha}$ H\"{o}lder continuous $p(x)$-harmonic functions in a bounded open domain $\Omega$ of $\mathbb{R}^n$, $n\geq 2$, provided that for each compact subset $K$ of $E$, the $(n-p_K+\alpha(p_K-1))$-Hausdorff measure of $K$ is zero, where $p_K=\max_{x\in K} p(x)$.
