Delta-points in Banach spaces generated by adequate families
Trond A. Abrahamsen, Vegard Lima, André Martiny
We study delta-points in Banach spaces generated by adequate families where . In the case the familiy is regular and…
Daugavet- and delta-points in Banach spaces with unconditional bases
Trond A. Abrahamsen, Vegard Lima, André Martiny +1
We study the existence of Daugavet- and delta-points in the unit sphere of Banach spaces with a -unconditional basis. A norm one element in a Banach space is a Daugavet-poin…
On octahedraliy and Müntz spaces
André Martiny
We show that every Müntz space can be written as a direct sum of Banach spaces X and Y , where Y is almost isometric to a subspace of c and X is finite dimensional. We apply this t…
Two properties of Müntz spaces
Trond A. Abrahamsen, Aleksander Leraand, André Martiny +1
We show that Müntz spaces, as subspaces of , contain asymptotically isometric copies of and that their dual spaces are octahedral.
