We continue the study of the fractional variation following the distributional approach developed in the previous works blow-up, asymptotics I and asymptotics II. We provide a general analysis of the distributional space $BV^{\alpha,p}(\mathbb{R}^n)$ of $L^p$ functions, with $p\in[1,+\infty]$, possessing finite fractional variation of order $\alpha\in(0,1)$. Our two main results deal with the absolute continuity property of the fractional variation with respect to the Hausdorff measure and the existence of the precise representative of a $BV^{\alpha,p}$ function.

Keywords: Hausdorff measure, Fractional Gradient, fractional divergence, fractional variation, fractional capacity, precise representative
