Henstock integral

Abstract

In this paper, we proved the basic properties of Henstock integral in the light of the basic properties of Riemann integral. Basic Theorem (i.e., N-L formula) doesn’t hold for all Riemann integral functions, but it holds for all Henstock integral functions, and we gave a proof of the extended result. By using small Riemannian sums on the small set, Henstock integrals are described, and it’s properties is given in another way, in addition, we gave an example that is not Henstock integral. At last, we proved that Henstock integral is just Riemann integral when satisfies some conditions.

Keywords: Riemannian integral; Henstock integral; Lebesgue integral; -fine spanision.
