The cardinality of the sublattice of closed ideals of operators between certain classical sequence spaces
Daniel Freeman, Thomas Schlumprecht, Andras Zsak
Theorem A and Theorem B of [1] state that for the lattice of closed ideals of , and of $\mathcal{L}(\ell_1,\…
Frame potential for finite-dimensional Banach spaces
J. A. Chávez-Domínguez, D. Freeman, K. Kornelson
We define the frame potential for a Schauder frame on a finite dimensional Banach space as the square of the -summing norm of the frame operator. As is the case for frames for H…
Closed Ideals of Operators between the Classical Sequence Spaces
Dan Freeman, Thomas Schlumprecht, Andras Zsak
We prove that the spaces , and of operators with have continuum many cl…
The discretization problem for continuous frames
Daniel Freeman, Darrin Speegle
We characterize when a coherent state or continuous frame for a Hilbert space may be sampled to obtain a frame, which solves the discretization problem for continuous frames. In pa…
A classification of continuous wavelet transforms in dimension three
Bradley Currey, Hartmut Führ, Vignon Oussa
This paper presents a full catalogue, up to conjugacy and subgroups of finite index, of all matrix groups that give rise to a continuous wavelet transf…
On spreading sequences and asymptotic structures
D. Freeman, E. Odell, B. Sari +1
In the first part of the paper we study the structure of Banach spaces with a conditional spreading basis. The geometry of such spaces exhibit a striking resemblance to the geometr…
