Using fractional calculus, we introduce an integral alongβ-Hölder rough paths for anyβ∈ (0,1]. This is a natural generalization of the Riemann–Stieltjes integral along smooth curves. We prove that, under suitable conditions on the integrand, this integral is a continuous functional with respect to the Hölder topology. As a result, this provides an alternative definition of the first level path of the rough integral along geometric Hölder rough paths.
