Journal Article 2025 03 15 In this work‎, ‎we prove that the set of all surjective bounded linear operators on a Banach function space in the context of a class of general sets, ‎is spaceable‎. ‎The obtained results not only prepare some new applications‎, ‎but also improve the previous versions given for standard Banach sequence spaces‎.
