New characterizations of the unit vector basis of $c_{0}$ or $ℓ_{p}$

Peter G. Casazza, Stephen J. Dilworth, Denka Kutzarova +1

Motivated by Altshuler's famous characterization of the unit vector basis of $c_{0}$ or $ℓ_{p}$ among symmetric bases, we obtain similar characterizations among democratic bases and…

Restricted invertibility of continuous matrix functions

Adrian Fan, Jack Montemurro, Pavlos Motakis +4

Motivated by an influential result of Bourgain and Tzafriri, we consider continuous matrix functions $A : R \to M_{n \times n}$ and lower $ℓ_{2}$ -norm bounds associated with…
