We apply the results established in fractional variation to prove some new fractional Leibniz rules involving $BV^{\alpha,p}$ and $S^{\alpha,p}$ functions, following the distributional approach adopted in the previous works blow-up, asymptotics I and asymptotics II. In order to achieve our main results, we revise the elementary properties of the fractional operators involved in the framework of Besov spaces and we rephraze the Kenig-Ponce-Vega Leibniz-type rule in our fractional context.

Keywords: Fractional Gradient, fractional divergence, fractional variation, Besov space, fractional Leibniz rule, Kenig-Ponce-Vega inequality, fractional Gauss-Green formula
