Abstract

A Riemannian approach of the PU integral is a Henstock type that is anchored with the concept of partition of unity. An integral of Pettis type, on the other hand, is essential, somehow, in formulating an integral in a Banach space. In this paper, the PU-Pettis integral will be formulated including some of its basic properties
