Abstract

Given a family C\mathcal{C} of closed bounded convex sets in a Banach space XX, we say that XX has the C\mathcal{C}-MIP if every CCC \in \mathcal{C} is the intersection of the closed balls containing it. In this paper, we introduce a stronger version of the C\mathcal{C}-MIP and show that it is a more satisfactory generalisation of the MIP inasmuch as one can obtain complete analogues of various characterisations of the MIP. We also introduce uniform versions of the (strong) C\mathcal{C}-MIP and characterise them analogously. Even in this case, the strong C\mathcal{C}-UMIP appears to have richer characterisations than the C\mathcal{C}-UMIP.
