From the text: “Riemannian sums were used in a definition of a nonabsolutely convergent integration on $$\mathbb{R}$$ almost fifty years ago and it was proved that the new integration is equivalent to Perron integration. Therefore it looked like there appeared just a new approach to integration. But the Riemannian approach proved to be very flexible: (i) it is the basis of numerous integrations of real functions of a real variable, (ii) it opens new ways in integration of functions of several variables, (iii) it is well applicable to integration of vector valued functions, (iv) it admits a great degree of abstraction. This paper is concentrated on (i) with a special accent on structures (convergence, topology) on the space of integrable functions. Section 5 contains a brief information concerning (ii).”
