THE PETTIS INTEGRABILITY OF BOUNDED WEAKLY MEASURABLE FUNCTIONS ON FINITE MEASURE SPACES

Since the concept of Pettis integral was introduced in 1938 [10], the Pettis integrability of weakly measurable functions has been studied by many authors [5, 6, 7, 8, 9, 11]. It is known that there is a bounded function that is not Pettis integrable [10, Example 10. 8]. So it is natural to raise the question: when is a bounded function Pettis integrable\ulcorner(omitted)
