Kurzweil–Stieltjes integration on compact lines
摘要
We develop a version of the Kurzweil–Stieltjes integral on compact lines and establish its fundamental properties. For sufficiently regular integrators, we obtain convergence theorems and establish a relationship to the Lebesgue integral with respect to positive Radon measures. Additionally, we introduce a notion of differentiation on compact lines which, when paired with the proposed integral, yields a formulation of the Fundamental Theorem of Calculus in this context.
