Quantitative bounds for unconditional pairs of frames
Peter Balazs, Daniel Freeman, Roxana Popescu +1
We formulate a quantitative finite-dimensional conjecture about frame multipliers and prove that it is equivalent to Conjecture 1 in [SB2]. We then present solutions to the conject…

Stability constants of the weak fixed point property for the space
Emanuele Casini, Enrico Miglierina, Łukasz Piasecki +1
The main aim of the paper is to study some quantitative aspects of the stability of the weak fixed point property for nonexpansive maps in (shortly, -fpp). We foc…

Weak Fixed Point Property in and Polyhedrality in Lindenstrauss Spaces
Emanuele Casini, Enrico Miglierina, Łukasz Piasecki +1
The aim of this paper is to study the -fixed point property for nonexpansive mappings in the duals of separable Lindenstrauss spaces by means of suitable geometrical propertie…
