New applications of extremely regular function spaces

Trond A. Abrahamsen, Olav Nygaard, Märt Põldvere

Let L be an infinite locally compact Hausdorff topological space. We show that extremely regular subspaces of C0​(L) have very strong diameter 2 properties and, for every rea…

Strongly extreme points and approximation properties

Trond A. Abrahamsen, Petr Hájek, Olav Nygaard +1

We show that if x is a strongly extreme point of a bounded closed convex subset of a Banach space and the identity has a geometrically and topologically good enough local approxi…

Two properties of Müntz spaces

Trond A. Abrahamsen, Aleksander Leraand, André Martiny +1

We show that Müntz spaces, as subspaces of C[0,1], contain asymptotically isometric copies of c0​ and that their dual spaces are octahedral.
