On certain subspaces of for and their applications to conditional quasi-greedy bases in -Banach spaces
Fernando Albiac, José L. Ansorena, Przemysław Wojtaszczyk
We construct for each an infinite collection of subspaces of that extend the example from [J. Lindenstrauss, On a certain subspace of , Bull. Acad. Po…
A dichotomy for subsymmetric basic sequences with applications to Garling spaces
Fernando Albiac, Jose L. Ansorena, Stephen J. Dilworth +1
Our aim in this article is to contribute to the study of the structure of subsymmetric basic sequences in Banach spaces (even, more generally, in quasi-Banach spaces). For that we…
Projections and unconditional bases in direct sums of spaces,
Fernando Albiac, Jose L. Ansorena
We show that every unconditional basis in a finite direct sum , with , splits into unconditional bases of each summand. This settles…
Embeddability of and bases in Lipschitz free -spaces for
Fernando Albiac, Jose L. Ansorena, Marek Cuth +1
Our goal in this paper is to continue the study initiated by the authors in [Lipschitz free -spaces for ; arXiv:1811.01265 [math.FA]] of the geometry of the Lipschitz fre…
Greedy approximation for biorthogonal systems in quasi-Banach spaces
Fernando Albiac, Jose L. Ansorena, Pablo M. Berna +1
The general problem addressed in this work is the development of a systematic study of the thresholding greedy algorithm for general biorthogonal systems (also known as Markushevic…
