利用分数阶微积分,对任意β∈(0,1],我们引入了一个沿沿着β-Hölder粗路的积分.这是沿沿着曲线的Riemann-Stieltjes积分的自然推广。我们证明,在适当的条件下的被积函数,这个积分是一个连续的功能方面的霍德尔拓扑。因此,这提供了沿着沿着几何Hölder粗糙路径的粗糙积分的第一级路径的替代定义。
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.
