Notes on the approximately continuous Henstock integral

Full-text: Open access


There are two different definitions about the approximately continuous Henstock integral or \(AH\) integral, for short. In this paper we prove that they are equivalent, and that the \(AH\) integral is included in the \(AD\) integral defined by Kubota in 1964. Also we give a solution for the problem put forward by Gordon (1994, p. 255).
