Henstock-Kurzweil Integral vs Stieltjes Integral
Developers should learn the Henstock-Kurzweil integral when working in advanced mathematical fields such as real analysis, functional analysis, or theoretical physics, where precise integration of irregular functions is required meets developers should learn the stieltjes integral when working in advanced mathematical fields such as probability theory, where it is used to define expectations with respect to cumulative distribution functions, or in functional analysis for studying linear functionals. Here's our take.
